<h5 id="id01328">THE MYSTERY EXPLAINED</h5>
<p id="id01329" style="margin-top: 2em">After dinner in the living-room of the Hostess House, a snapping,
dancing, crackling fire in the grate, and the girls gathered in an
expectant semicircle about it.</p>
<p id="id01330">They were nervous, too, for every once in a while one of them would
get up, look out the window, throw an extra log upon the fire and sit
down again with a "why-don't-they-come?" look of impatience upon her
face.</p>
<p id="id01331">A ring at the door bell!</p>
<p id="id01332">"I'll answer it," cried Betty, jumping up and nearly overturning a
chair in her eagerness. When she returned a couple of minutes later,
her face held a look of unutterable disgust.</p>
<p id="id01333">"Only one of the guests," she said, as the girls looked up eagerly.<br/>
"I was sure that must be the boys."<br/></p>
<p id="id01334">"They're terribly late," grumbled Mollie, kicking an overturned edge
of the rug into place, as if even that small vent to her feelings was
a relief. "They'll be all talked out before they get here."</p>
<p id="id01335">Another ring at the door bell!</p>
<p id="id01336">This time there was no mistake. A chorus of excited voices greeted
Betty as she opened the door for them and a moment later the boys
burst into the living-room, fairly exhaling importance. The girls
welcomed them eagerly and drew up more chairs before the fire.</p>
<p id="id01337">"Gee, but we've had some time," cried Allen, fairly panting from
exertion and excitement. "If you girls were heroines before, you're
more than ever so, now."</p>
<p id="id01338">"But where's Will?" asked Grace, with that old, anxious look. "I
thought he was coming with you."</p>
<p id="id01339">"He is," Frank answered her. "But he was summoned to a very important
conference with the colonel——"</p>
<p id="id01340">"The colonel!" they cried incredulously, while Grace stamped her foot
with impatience.</p>
<p id="id01341">"What do you mean?" she demanded.</p>
<p id="id01342">"Just that," he answered, enjoying their mystification too much to
enlighten them at once. "When he received the order he told us
fellows to come on over and he'd join us as soon as he could break
away."</p>
<p id="id01343">"Oh, Allen, please tell me what it all means." Grace was fairly
crying with excitement and eagerness. "Please don't keep me waiting
any longer!"</p>
<p id="id01344">"I'm sorry, Grace—I didn't think," said Allen, in quick compunction.
"It means," he added, with a ring of pride in his voice, "that Will
is what we always believed him to be—one of the finest fellows that
ever lived. I'm proud to be called his friend!"</p>
<p id="id01345">"Oh, Allen!" Grace felt blindly for a handkerchief and Betty slipped
it into her hand. "Oh, Allen,——"</p>
<p id="id01346">"But what did he do?" demanded Mollie impatiently. "You haven't
gotten to the point yet."</p>
<p id="id01347">"Well," Allen continued, while Betty put a sympathetic arm about her
friend and snuggled close, "all the time we were wondering down in
our hearts why Will didn't enlist—although we never doubted he had
good reasons," he added hastily, "he was really working harder,
spending more time and energy for the government than we ever thought
of spending. There's one important thing we forgot—that Will was a
secret service man!"</p>
<p id="id01348">"Oh!" cried Betty, her eyes gleaming in the firelight, "now, I know I
guessed right!"</p>
<p id="id01349">"What did you guess?" asked Allen, remembering to marvel, even in
that moment of excitement, how very becoming firelight was to Betty!
"Out with it."</p>
<p id="id01350">"Why," said Betty, leaning forward eagerly, "after Amy told us that
she had met Will and the soldiers half way to the spot where we found
the spy, I seemed to see the whole thing as plainly as if some one
had told it to me.</p>
<p id="id01351">"I remembered Will's special interest in the spy the first time we
met Adolph Hensler on Pine Island—then how, soon after we saw him
here again, Will wrote Grace that he was coming on. That would seem
as though he were hot on his trail—"</p>
<p id="id01352">"He was," said Allen, while the others hung on every word.</p>
<p id="id01353">"Well, the rest is simple," said Betty. "I suppose that Will kept on
shadowing him till he got what he wanted. He was on his way to
capture the spy, while we were hanging on to the door, praying for
help. Oh, it all fits together like parts of a puzzle!"</p>
<p id="id01354">"You're a wonder, Betty!" said Allen, while the others drew a deep
breath, trying to take it all in. "But there was one little bit, or
rather, I should say, big bit, of cleverness on Will's part that
neither you nor anybody else could guess at. You remember the code
letter we picked up that night on Pine Island?"</p>
<p id="id01355">"Yes," they cried eagerly.</p>
<p id="id01356">"Well, Will had the code deciphered and found out who wrote the
document. It proved, by the way, that Adolph Hensler is one of the
most dangerous and most wanted German spies in this country."</p>
<p id="id01357">"And what else?" cried Mollie, who could never wait for the end of a
story.</p>
<p id="id01358">"The clever part of it," Allen continued, leaning forward, very
handsome and eager in the firelight, "was Will's copying of the
handwriting on the envelope."</p>
<p id="id01359">"Sure," chuckled Roy. "I told him I wouldn't be surprised to see him
start a life of crime any time now."</p>
<p id="id01360">"Surely no experienced forger could have done it better," Allen
agreed whimsically, while the girls waited with unconcealed
impatience. "Anyway, he wrote a short note—a decoy—to Adolph in
this handwriting, requesting an interview at the very spot where you
girls came upon him."</p>
<p id="id01361">"Oh!" cried Betty, in dismay. "Then it would have been better if we'd
left him alone. We took a chance of spoiling all Will's well-laid
plans."</p>
<p id="id01362">"How could it have been better?" asked Allen. "Will started out to
capture him and found you girls had beat him to it, that's all."</p>
<p id="id01363">"Yes and they might have had a good deal more trouble rounding him up
than you did," put in Frank. "From what Will tells us, you girls sure
did do a neat job."</p>
<p id="id01364">The girls flushed with pleasure, but Mollie, being truthful to a
fault, put an arm about Betty and told where most of the credit was
actually due.</p>
<p id="id01365">"Why, it was Betty who thought of cutting him off," she said, while
Betty vainly tried to stop her. "No, I'm going to tell the truth! And
it was Betty that really captured him. She saw him go in the door,
followed him, and was holding on for dear life when we came upon
her."</p>
<p id="id01366">"Yes, and how long would I have been able to hold on, I'd like to
know," protested the Little Captain vigorously, "if you girls hadn't
come along just then. No, sir, if there's any credit at all, it's got
to be divided equally among us!"</p>
<p id="id01367">"You'll be surprised to see how much credit everybody's giving you,"
chuckled Roy. "When you make your next debut into society, I wouldn't
be surprised if they greeted you with brass bands."</p>
<p id="id01368">"Goodness, I wish they would," cried Mollie eagerly. "For the first
time in my life, I'd have a chance to feel like a regular soldier!"</p>
<p id="id01369">"But Will is the real hero," said Betty quietly. "To go on working
for your county, taking a chance on having people think things of you
that you don't deserve, that sort of thing is the real heroism."</p>
<p id="id01370">"And I'm so glad and happy," added Grace, who had been seeing happy
visions in the firelight, "to think that all his friends had faith in
him when he most needed it."</p>
<p id="id01371">"You bet we did," said Allen heartily. "There wasn't one of us who
doubted him for a minute."</p>
<p id="id01372">"I wonder when he'll get here," said Amy, rising slowly and strolling
over to the window. "I hope the colonel lets him out before twelve
o'clock."</p>
<p id="id01373">"Oh, he'll be here almost any minute now," said Allen reassuringly.
"Meanwhile, suppose you play something for us, Betty—something soft
and sweet to match the firelight—and you," this last so softly that
none but Betty heard.</p>
<p id="id01374">Smiling a little, Betty rose and walked over to the piano. Allen
followed her.</p>
<p id="id01375">"What shall I play?" she asked, looking up at him with a sweet
seriousness, that made him want desperately to gather her in his arms
and tell her—oh, so many things! Instead, he said:</p>
<p id="id01376">"Play 'Keep the Home Fires Burning.' It's the most appropriate thing
to-night. And Betty, sing it—sing it—to me——"</p>
<p id="id01377">"If I can," she murmured. "You know what happened when I tried to
sing it before—and it's apt to be harder to-night."</p>
<p id="id01378">"Try, anyway," he urged; and so she began, in the sweetest voice in
the world, or so Allen thought, to sing one of the most beautiful
songs ever composed.</p>
<p id="id01379">And how she sang it! Before she had half finished it, the girls were
feeling for their handkerchiefs and the boys were staring hard into
the fire.</p>
<p id="id01380">She sang it again—more softly than before, and when the last sweet
note had died away, there was not a dry eye in the room.</p>
<p id="id01381">"Betty, oh, Betty!" cried Allen, leaning across the piano toward her,
thrilling her with the new earnestness in his voice, "will you keep
the home fires burning for me—so that when I come back—Betty, when
I come back——"</p>
<p id="id01382">She nodded, not trusting herself to speak, and held out a trembling
hand to him.</p>
<p id="id01383">"There will always be one—waiting for you," she whispered softly.</p>
<p id="id01384">"Hello, folks!"</p>
<p id="id01385">They turned suddenly and found Will standing in the doorway. Then,
such a welcome as they gave him! It made up to him for all these
months when he had seemed to stand on the outside, looking in.</p>
<p id="id01386">"Come over to the fire and tell us all about it," Betty commanded.
"Allen told us something, but we want to know the whole story—every
little bit of a detail."</p>
<p id="id01387">Will fairly beamed and entered into the story with the greatest
enthusiasm.</p>
<p id="id01388">"I really didn't do anything much," he finished modestly. "And at the
end it was you girls that did all the work. I was just an 'also
ran.'"</p>
<p id="id01389">"But, isn't there something you left out?" drawled Frank, pretending
to yawn and gazing into the fire. "It seems to me——"</p>
<p id="id01390">"Gee," said Will, surprised at himself, "if I didn't really forget
the most important part——"</p>
<p id="id01391">"Now what are you talking about?" cried Mollie, while the girls
pricked up their ears and began to scent a new mystery. "What did you
forget?"</p>
<p id="id01392">"Well," said Will, his eyes twinkling, and speaking with exasperating
slowness, "do you happen to remember an eventful night on Pine
Island, when Roy went to sleep——"</p>
<p id="id01393">"Aw, cut it out," grumbled Roy. "I guess I'll never be able to live
that down."</p>
<p id="id01394">"Well, what about it?" cried Betty, at the limit of her patience,
while the other girls looked threatening. "Please, Will——"</p>
<p id="id01395">"Do you happen to remember," drawled Will, "that on that same night
you lost some jewelry?"</p>
<p id="id01396">"Oh, you found it!" they cried, fixing him with four pairs of bright,
incredulous eyes. "Will, where is it?"</p>
<p id="id01397">"Some of it's here," he went on, pulling a small bag from his pocket
and opening it carefully while they crowded around him, fairly
smothering him in their eagerness, "and the rest of it's in the pawn
shop. We found the tickets on him, though—"</p>
<p id="id01398">"My watch!"</p>
<p id="id01399">"My necklace!"</p>
<p id="id01400">"My lavallière!"</p>
<p id="id01401">"My pearl brooch!"</p>
<p id="id01402">These and other exclamations like them made such a babel of sound
that the boys clapped their hands over their ears and looked at one
another in comic dismay. This lasted so long that the boys had to
pick up their caps and start for the door, before the girls consented
to notice them.</p>
<p id="id01403">"Where are you going?" asked Betty, while the other three stopped
talking long enough to look surprised.</p>
<p id="id01404">"We didn't think you'd miss us," said Roy plaintively. "So we were
going away from here—that's all."</p>
<p id="id01405">"Now, who's a flock of geese, I'd like to know," laughed Betty, as
they coaxed their neglected swains back to the fire. "We couldn't
very well help being excited, could we?"</p>
<p id="id01406">"And to think," said Grace, beaming, "that we not only helped to
catch a wanted spy, but helped to recover our own jewelry at the same
time!"</p>
<p id="id01407">"No wonder we had to pat ourselves on the back," chuckled Mollie,<br/>
"Just wait till we tell the folks at home about it."<br/></p>
<p id="id01408">"Pretty good day's work," Roy admitted indulgently. "Couldn't have
done much better myself."</p>
<p id="id01409">They fell silent after that, each one busy with his own thoughts,
each one seeing, in the fantastic, ever-changing heart of the fire, a
little of his or her own future. And they were very happy.</p>
<p id="id01410">Suddenly Grace broke the silence.</p>
<p id="id01411">"And now," she said, glancing with love and pride at Will, who smiled
fondly back at her, "what do you expect to do, dear?"</p>
<p id="id01412">"Enlist," cried Will, jumping to his feet. "Thank heaven I can do it
now with a clear conscience. I'm going to get into the big game quick
and help give Fritz some of his own medicine. Gee, fellows, are we
going to do it—are we?"</p>
<p id="id01413">"I should smile!" they cried, their eyes gleaming with anticipation.<br/>
"All we want is the chance!"<br/></p>
<p id="id01414">Quick as a flash Betty ran to the piano and began to play the
"Star-Spangled Banner." Instantly the others were on their feet and
singing with all the pent-up fervor of the last six months, emotions
almost too big to master finding expression in the stirring melody.</p>
<p id="id01415">"And we're all in it together," cried Betty, eyes bright and cheeks
flaming, "for our dear country—for America!"</p>
<p id="id01416">And, at the greatest moment of their lives, fired by patriotism,
confident of victory, we once more, slowly, reluctantly, with many
backward glances, take leave of our Outdoor Girls.</p>
