<div>A COLD DRAFT</div>
</div></div>
<p class='c014'>The loud-speaker’s bellow died away and there was
an answering stir in the big terminal building of the airport.
People began to move toward the wide windows
that overlooked the landing field. Soon there was a thick
wall of humanity packed against the rail that protected
the glass.</p>
<p>“Too jammed up here. Let’s go outside.” The young
man who spoke was slender and slightly more than
medium height. Over a neat gray flannel suit he wore a
tan trench coat which hung well from broad shoulders.
His black hair looked even blacker than usual in the
brilliant glare of the well-lighted room.</p>
<p>His companion towered over him by almost half a
foot. A trench coat, also tan, dropped from massive
shoulders that hinted of tremendous power. He lifted his
left hand to look at his wrist watch. “On time,” he said.
Then, using his shoulders as a wedge, he gently forced
a path to the doors. His flaming red hair stood out above
the crowd like a beacon.</p>
<p>Outside, in the crisp December afternoon, the air
was filled with the heavy throb of plane motors. Overhead,
a silver ship was wheeling into the wind, landing
gear down.</p>
<p>The loud-speaker came to life again. “Flight two-oh-six,
from Paris,” it intoned, “now landing.”</p>
<p>Sandy Allen, the huge redhead, touched his friend’s
arm. “Feels good to have him coming home for Christmas,
huh?”</p>
<p>Ken Holt grinned briefly, his eyes steadily riveted on
the plane now zooming toward them down the paved
strip. “And how!”</p>
<p>“If I had any sense,” Sandy said, “I’d fade out on an
occasion like this. It isn’t often that you and your
father—”</p>
<p>“If you had any sense,” Ken interrupted, “you’d remember
that if it weren’t for the oversized Allen clan I
might not even—”</p>
<p>The deafening roar of engines cut off the rest of his
sentence, but Sandy’s face had already begun to redden.
He could take almost anything except gratitude, and
he hated to be reminded of the circumstances in which
he and Ken had first met. Ken’s father had been in desperate
danger then, and the entire Allen family—Pop,
Bert, Sandy, and Mom—had taken part in the frightening
hours of action that followed their meeting.</p>
<p>Afterward, Ken Holt, motherless for years, had left
his boarding school at the Allens’ insistence to make his
home with them. Mom Allen treated him like another
son, and Pop Allen had given Ken a part in the operation
of the Allen-owned newspaper, the Brentwood
<i>Advance</i>.</p>
<p>Ken and Sandy had shared many adventures since
then; had encountered many exciting and dangerous
puzzles which they had solved together. They worked
as a team, both in unraveling mysteries and in reporting
them afterward. Ken’s stories and Sandy’s photographs
had been eagerly accepted not only by the
<i>Advance</i>, but also by Global News, the gigantic news-gathering
agency for which Ken’s father, Richard Holt,
worked.</p>
<p>Ken glanced up at Sandy’s flushed face. “Relax,
chum,” he said. “I won’t say another word about how
much I owe—”</p>
<p>Sandy clamped his huge hand over Ken’s mouth. “I’ll
say you won’t.” He grinned. “In return for your silence—something
we rarely get from you,” he went on, “I’ll
let you in on a secret.” He removed his hand and
reached into his pocket.</p>
<p>“What secret?” Ken asked suspiciously.</p>
<p>“You remember that last little mess we got into—the
one Pop called <i>The Secret of Hangman’s Inn</i>?”</p>
<p>“I’d just as soon not remember that,” Ken said.</p>
<p>“Have it your own way.” Sandy had pulled a piece of
paper out of his pocket. “In that case you won’t want
your half of this check from Global for the yarn and the
pictures we sent them.”</p>
<p>Ken grabbed for the check and looked at it. “What
do you know!” he murmured. “A hundred and fifty
dollars! Granger must be getting soft in the head.”</p>
<p>“Granger,” Sandy said loftily, “is a top-flight news
editor. He appreciates the remarkable quality of my
pictures. He’d probably make it two hundred if he
didn’t have to wade through that stuff you call writing.”</p>
<p>Ken handed the check back to Sandy. “Pictures,” he
said, “are something anybody can take. But writing—real
writing—” Suddenly he broke off. “There’s Dad!”</p>
<p>Richard Holt had just stepped out of the plane, first
in the line of passengers descending the stairway. He
was a slender figure in a rumpled topcoat, with a brief
case clamped under one arm. The other arm raised in
a swift salute as he spotted them.</p>
<p>“Hi!” he shouted.</p>
<p>“Dad!” Ken’s answering shout carried far across the
field. His father spent most of his time in distant quarters
of the globe, ferreting out the stories that had made
him famous. His visits home, brief and infrequent,
were always exciting. The Allens enjoyed them as much
as Ken himself did, and this year they were all particularly
pleased at the thought of having Richard Holt
at hand over the holidays.</p>
<p>“We’ll meet you outside the customs office,” Ken
called, as his father drew nearer.</p>
<p>Richard Holt nodded, smiling.</p>
<p>“Come on!” Ken said to Sandy, and they turned back
through the crowd. “It won’t take him long to clear
customs. They know him by now.”</p>
<p>Twenty minutes later Richard Holt came through the
barrier to where they were waiting for him. He dropped
two bags and his brief case and threw an arm around
each of the boys. Then he stood back a pace to look
them over.</p>
<p>“Are you two as good as you look?” he demanded,
grinning widely.</p>
<p>“We’re even better,” Sandy assured him, scooping
up both the bags. “You look O.K. too.”</p>
<p>“You look great, Dad,” Ken said.</p>
<p>“I am. And glad to be home too.”</p>
<p>“This is our first Christmas together in three years.”
Ken groped for the brief case, but his eyes never left
his father’s face.</p>
<p>“We’ll make it a good one, son.”</p>
<p>Sandy began to lead the way to the parking lot. “If
food will help,” he said, “I think you can count on Mom.
Wait until you see the turkey she’s got!”</p>
<p>“With cranberry sauce?” Richard Holt asked.</p>
<p>Sandy nodded. “Also with dressing, sweet potatoes,
plum pudding—”</p>
<p>“Stop!” Ken’s father commanded. “Let us waste no
more time talking. On to Brentwood! That is,” he corrected
himself, as he came to a halt beside the boys’
red convertible, “on to Brentwood after a quick stop
at my apartment. I want to get rid of some of this luggage
and change my clothes. I’ll sit in the back seat with
the bags, if you don’t mind,” he went on, “so I can be
sorting out the things I want to take with me. It’ll save
time.”</p>
<p>Sandy started the motor and the car slid smoothly
into the line of traffic heading for New York City.
Forty-five minutes later he pulled to a stop before the
building in which Ken’s father maintained his seldom-used
apartment.</p>
<p>“Give me five minutes,” Richard Holt said.</p>
<p>“Shall I carry your bags up, Dad?” Ken asked.</p>
<p>“I’ve got them.” The correspondent swung one in
each hand. “They’re considerably lighter than they
were.” He nodded toward a heap of packages on the
back seat. “Don’t go snooping in those things while I’m
gone.”</p>
<p>“Word of honor,” Ken said, grinning.</p>
<p>Richard Holt was back at the car again in six minutes
flat. “O.K., men,” he said, sliding into the front seat beside
Ken. “Head for Brentwood—and don’t spare the
horsepower.”</p>
<p>“Aye, aye, sir.” Sandy let the car move forward. A
moment later he was heading southward toward the
Holland Tunnel and New Jersey across the Hudson
River.</p>
<p>“Now,” Mr. Holt said, settling himself comfortably,
“you can begin to tell me what Mom’s preparing
for tonight. After all, the Christmas turkey is still two
days away. She doesn’t expect me to fast until then, I
hope.”</p>
<p>“Not quite,” Sandy assured him. “For tonight she’s
got—”</p>
<p>Several hours later Richard Holt shoved his chair
back from the Allen dinner table and sighed luxuriously.
“Sandy didn’t exaggerate a bit,” he assured Mom Allen.
“My only worry now is recovering my appetite in time
for the turkey.”</p>
<p>Mom’s eyes twinkled at him. “One good way of working
off a meal is to wash the dishes, Richard.”</p>
<p>“Now, Mom,” Pop protested. “Dick’s a guest.”</p>
<p>“I always think of him as a member of the family,”
Mom said.</p>
<p>“Thank you, Mom,” Richard Holt said. “It’s an honor—even
if it does make me eligible for dishwashing.”</p>
<p>Mom stood up. “Then that’s settled. I’ll just leave
everything in your capable masculine hands, while I
run down the street to visit with my sister for a while.”</p>
<p>Bert grinned. “That’s where Mom’s hoarding her
presents,” he explained to Richard Holt. “She doesn’t
trust us.”</p>
<p>“I have my reasons,” Mom assured him as she departed.</p>
<p>Sandy washed, Ken dried, and Bert stacked the dishes
in their places in the cupboard. Pop and Ken’s father
stood on the side lines to give what Pop called their
“invaluable advice.” Within half an hour the job was
done.</p>
<p>As Ken flipped his dish towel over the rack, he said,
“Do you want some paper and ribbon and stuff for
wrapping up those packages you brought, Dad? We’ve
got plenty.”</p>
<p>“Fine,” his father said. “I was just thinking they didn’t
look very festive in the old newspapers I’ve got wadded
around them.”</p>
<p>Pop took his pipe out of his mouth. “You know, Dick,
we Allens follow the custom of opening presents on
Christmas Eve. Hope this isn’t opposed to your own
tradition.”</p>
<p>“It suits me fine.” Mr. Holt smiled. “Means we can
sleep later on Christmas morning—and work up more
strength for the turkey.”</p>
<p>Ken brought out the cardboard box of wrappings he
had found in a closet. “Want me to bring the packages
down from your room, Dad?” he asked, with a great
show of innocence.</p>
<p>“Not on your life,” his father told him. “You can just
wait until tomorrow night to see what’s in them.” He
started for the stairs himself.</p>
<p>“I’ll give you a hand,” Bert offered, when Richard
Holt had returned with the packages.</p>
<p>“Don’t let him,” Sandy advised. “It’s a trick. He just
wants to poke around.”</p>
<p>The foreign correspondent grinned. “I need help, all
right. I’m no good at this.” He picked up the largest of
the various bundles. “But this one is yours, Bert, so
don’t touch it.”</p>
<p>“I’ll wrap that one,” Pop offered.</p>
<p>“Thanks.” Mr. Holt hefted two parcels of almost
equal size, and finally handed one to Sandy. “That’s
Pop’s—and don’t drop it.” He handed the other to Bert.
“That’s Sandy’s—and that had better not be dropped
either.”</p>
<p>Ken eyed the two packages still on the table. “Which
is Mom’s? I’ll do hers.”</p>
<p>“Let that wait for last,” his father said. “I want a
conference on it. In the meantime—” He took up the
smaller of the two remaining parcels and set to work
on it himself.</p>
<p>When they were all finished, Richard Holt began to
tear the heavy newspaper wrapping from the final
parcel. “Take a look at this, will you?” he asked. “If you
don’t think Mom will like it, I’ll get her something else
tomorrow. I don’t feel very satisfied with it myself.”</p>
<p>The last sheet of paper fell away to disclose a small
iron box, about eight inches long, four inches wide, and
four inches deep. The surface was heavily ornamented
with scrollwork, and its considerable weight was evident
from the way Ken’s father held it.</p>
<p>“I thought,” he said half-apologetically, “that she
could line it with velvet or something and use it for a
jewel box. But I don’t know much about such things.
Maybe you can suggest something else she’d rather
have.”</p>
<p>“She’ll love it,” Pop said decisively. “She loves old
things—antiques. And this sure looks old.”</p>
<p>“I think it’s old enough,” Richard Holt said. “Several
hundred years, I’d guess. It was probably made originally
to be used as a sort of home safe-deposit box.”
His finger pressed one of the curlicues on the front of
the box and the lid sprang open.</p>
<p>“Hey!” Sandy exclaimed admiringly. “A secret
catch!”</p>
<p>“May I try it?” Bert asked. “Beautiful workmanship,”
he muttered, as his fingers explored the front. Finally
he found the proper curlicue and again the lid flew
open.</p>
<p>Sandy tried it next, and then Pop and then Ken.</p>
<p>“No doubt about it,” Sandy said finally. “Mom’ll be
crazy about it. She likes secrets as much as she likes
antiques.”</p>
<p>Ken, about to hand the box back to his father, saw
that Richard Holt’s hands were occupied with lighting
a cigarette. So he put the box, instead, on the platform
of Mrs. Allen’s kitchen scale, near at hand on the shelf.
The indicator of the scale swung sharply over.</p>
<p>“Look,” Sandy said. “Four and a half pounds even.
It weighs a lot for such a little thing.”</p>
<p>“They didn’t skimp on materials in those days,” Pop
said. “Where’d you get hold of it, Dick?”</p>
<p>“One of the porters in the Global office in Rome
asked me if I wanted to buy it,” the foreign correspondent
answered. “I knew he’d been selling some of his
family heirlooms—he has a hard time getting along—and
I wanted to help him out. I persuaded myself at
the time that it would do for Mom’s present, but later
I had some qualms about it. I thought maybe I should
have shopped around, instead of just taking something
that fell into my hands. But if you think it’s all right—”</p>
<p>He cleared a space on the kitchen table, spread out
a sheet of wrapping paper, and reached for the box.
As he picked it up, it slipped from his fingers, struck
the edge of the cupboard a glancing blow, and crashed
to the floor. The lid sprang open.</p>
<p>Sandy and Ken both dived for it as Richard Holt
muttered, “That was stupid of me.”</p>
<p>“It can’t be hurt,” Pop said. “It’s made too solidly.”</p>
<p>Mr. Holt pressed the lid into place, but when he took
his hand away it opened again. He tried a second time.
Once more the lid refused to stay closed.</p>
<p>Five heads bent over to study the tiny mechanism.</p>
<p>Bert touched the little spring catch. “That’s what’s
wrong,” he said. “The little lever is bent out of shape.”</p>
<p>“Maybe I can fix it,” Sandy offered.</p>
<p>“Better not try,” Pop cautioned. “An expensive antique
like that—”</p>
<p>“It wasn’t expensive, I assure you,” Richard Holt
said. “It—”</p>
<p>“Never mind,” Pop said. “It’s an antique and I don’t
think anybody but Sam Morris ought to touch it. He’s
the best jeweler in town. He can fix anything.”</p>
<p>Sandy offered to telephone Morris to see if he could
take care of the job that evening. When he returned
from the hall he reported that the jeweler was just then
closing his shop, but that he had promised to repair the
box the next day despite the rush of orders that always
claimed his attention on Christmas Eve.</p>
<p>“So let’s just get it out of sight before Mom comes
home,” Pop said. “Then you boys can take it down to
him first thing in the morning.”</p>
<p>“How’s this?” Bert asked, dumping an assortment of
Christmas seals out of a shoe box. “You can put it in
here.”</p>
<p>When the little box was inside, he snapped a rubber
band around the cardboard container and scrawled on
the cover “Mom—Don’t peek!”</p>
<p>“And we’ll leave it right here,” Bert said, placing it
in full sight on the sideboard.</p>
<p>“What’s the idea?” Richard Holt wanted to know.</p>
<p>Pop grinned. “Just teasing her.”</p>
<p>“She’ll try to wheedle a hint out of us—without ever
asking a direct question,” Bert said.</p>
<p>“But she won’t look inside,” Sandy added.</p>
<p>“Sounds like some form of torture to me,” Ken’s
father said.</p>
<p>“It is,” Sandy admitted, grinning. “But it’s an old
Allen custom—only usually we’re on the receiving end.”</p>
<p>But Mom, when she returned a little later, refused
to give them the satisfaction of a single question. She
did walk past the sideboard several times, but they
could never catch her looking directly at the box. And
once, when she had to move it aside to make room
for her morning’s setting of rolls, she seemed not
even to notice that the shoe box was a stranger in her
kitchen.</p>
<p>Richard Holt grinned at the Allens, and they grinned
sheepishly back at him. “If there’s any teasing going
on around here,” he said quietly, “I don’t think we’re
doing it.”</p>
<p>“Did I hear you say you wanted a cheese sandwich?”
Mom said. Her eyes were twinkling.</p>
<p>“Eh—why, yes, I believe I could manage one—even
after all that dinner,” Richard Holt admitted.</p>
<p>Some time later, as Sandy crawled into bed and
snapped of the light at his elbow, he murmured his
usual last request to Ken. “Don’t forget to open the
window.”</p>
<p>Ken slid the frame up several inches and shivered as
the cold air struck him. “It’s snowing,” he said.</p>
<p>There was no answer. Sandy was already asleep.</p>
<p>But Ken was still wide awake ten minutes later. He
turned over and tried counting sheep, but the ruse
didn’t work.</p>
<p>“Serves me right,” he muttered, “for eating that
cheese sandwich.” He turned over once more.</p>
<p>When another ten minutes had gone by he slid out
from under the covers.</p>
<p>“A good dull book—that’s what I need,” Ken decided.
“And Pop’s got plenty of them in his library
downstairs.”</p>
<p>In his robe and slippers he cautiously opened the
bedroom door and stepped out into the silent hallway.
As he moved toward the stairway he slid one hand
along the wall to feel for the hall-light switch.</p>
<p>Suddenly he stopped. A cold draft was swirling
around his feet. He was just deciding that he hadn’t
pulled the bedroom door tight shut when something
else caught his attention. Below him, in the darkness,
a faint click sounded.</p>
<p>And almost immediately the draft around his feet
died away.</p>
<p>Ken’s hand moved swiftly then. His fingers found
the switch and the hall light snapped on. Ken took the
two descending steps to the turn in a single quiet leap.
But before he could start down the rest of the flight he
heard another click from downstairs, and felt another
surge of cold air around his feet. A third mysterious
click sounded just as he reached the bottom of the stairs.</p>
<p>Ken snapped on all three switches on the wall of the
lower hallway. The hallway itself, the living room, and
the sun porch all became brightly illuminated.</p>
<p>But the light revealed nothing to his searching eyes.
The rooms looked just as they had looked some time before,
when the Allens and Holts had gone upstairs to
bed. He went through the dining room, into the kitchen,
and into the pantry, turning on all the lights as he went.
But nowhere was there any sign of disturbance, or of
an intruder who might have been responsible for those
clicking sounds.</p>
<p>Ken shook his head. “Was I dreaming? I certainly
thought I heard something down here. And it sounded
like the front door opening and closing.”</p>
<p>Finally he turned off all the lights, picked up his book,
and started back toward the stairs. But at the foot of
them he stopped. That cold draft around his feet
couldn’t have been a dream.</p>
<p>Ken moved swiftly to the front door. It was securely
locked. He started for the kitchen door and then turned
back.</p>
<p>He snapped on the front entrance light and pulled
the curtain away from the glass panel in the door in
order to peer out.</p>
<p>His breath caught sharply. Footprints stood out
clearly on the snow-covered porch. And through the
veil of falling snow, for as far as the light penetrated,
he could see further footprints—on the porch steps and
on the flagstone walk that crossed the lawn to the sidewalk.</p>
