<h2>CHAPTER XVI. <br/> <small>THE TIRE PRINTS.</small></h2>
<p>Jack Cray barely avoided a sudden start at that last
remark of Mrs. Simpson’s. He had been hoping for
some light on the electric car, but had thought it improbable
that he would find any clew at the fugitive’s
home.</p>
<p>“So he’s a fool at times, is he?” he thought. “Good
enough! That ought to make things easier.”</p>
<p>“So the bug caught him, too, did it?” he asked
aloud, with a careless smile. “Did he buy a machine?”</p>
<p>“Oh, no, sir! He rented one in the village, but
his idea was to buy one as soon as he could afford it.
In fact, he has had a gate made in the back fence, and
one of those little, portable garages put up.”</p>
<p>“He meant to enjoy himself, didn’t he?” Cray
asked lightly, though the role he was obliged to play
was becoming more and more irksome. “There’s a
driveway at the side of the house, though, isn’t there?
I thought I noticed one as I came in.”</p>
<p>“Yes, there is,” Mrs. Simpson agreed. “That was
another queer thing. I didn’t see how in the world
John was going to afford a car—even a secondhand
one, as he talked of buying—but if he was going to
have one, I didn’t see why it should not be driven in<span class="pagenum"><SPAN name="Page_80" id="Page_80">[80]</SPAN></span>
from the front, since that was what the drive was
made for. He wouldn’t hear of it, though.”</p>
<p>“Why not?”</p>
<p>“He said he was going to drive his own car, and he
didn’t want everybody to be watching him and criticizing
the way he was doing it. He thought he would
prefer to come in the back way, where there wouldn’t
be so many spectators. That was ridiculous, though,
because you can see for yourself that there are not
many people living here on the hill. Besides, he would
soon have learned to drive well enough not to mind
if he were watched.”</p>
<p>Cray nodded, but his heart was pounding. This
was certainly a queer whim on Simpson’s part, and
the detective was sure there must be some reason for
it. In fact, he was inclined to believe that there was
a reason for the choice of the house itself, and that
both had to do with the fugitive’s crime. The thought
was an exciting one, but Cray was at a loss to explain
Simpson’s actions.</p>
<p>It might be well to see how the land lay, and the
best way to do that, he believed, was with Mrs. Simpson’s
knowledge, rather than furtively.</p>
<p>“I don’t want to alarm you too much,” he said, “but
these things look rather queer, you know. You seem
sure that there wasn’t anything the matter with Mr.
Simpson’s mind, and yet you admit that he has done
some peculiar things. You’d rather think that his
mind was temporarily clouded, wouldn’t you, than that
he was dead, or had deliberately left you in the lurch?”</p>
<p><span class="pagenum"><SPAN name="Page_81" id="Page_81">[81]</SPAN></span></p>
<p>“Of course,” Mrs. Simpson agreed. “It would be
terrible, though—terrible!”</p>
<p>“So are the other possibilities,” Cray pointed out.
“Let’s work along this line—for a while. Would you
mind letting me see this gate and garage you speak
of?”</p>
<p>“No, certainly not,” the woman said, but it was plain
that she thought the proceeding a senseless one. “I’ll
show you.”</p>
<p>The lot was perhaps sixty feet wide, and one hundred
and fifty feet deep, possibly more. The grass
had not yet obtained a fair start, and the shrubs and
trees were very small, although they had evidently been
planted the season before.</p>
<p>The gravel drive ran along one side of the lot, from
front to rear, and beside it, close to the rear fence, was
the little, portable garage of which Mrs. Simpson
had spoken. It was built of metal, as a precaution
against fire, and when the detective tried the door, he
found it locked.</p>
<p>“Your husband has the key, I suppose?” he said.</p>
<p>“Yes, sir.”</p>
<p>Cray had noted the graveled surface of the drive on
his way from the house, and had seen that it had not
been used. There were footprints on the soft surface,
but no evidence of tires.</p>
<p>“The garage has never been used, I suppose?” Cray
inquired.</p>
<p>“Oh, no, Mr. Jones.”</p>
<p>“And no car has been driven into the yard?”</p>
<p>“No, sir.”</p>
<p><span class="pagenum"><SPAN name="Page_82" id="Page_82">[82]</SPAN></span></p>
<p>There was no doubt that she was telling the truth,
so far as she was aware, but Cray had evidence that
she was mistaken. To be sure, no car had been driven
in from the front, but it was plain that one had entered
the yard through the new back gate.</p>
<p>Evidently the machine had not entered the garage,
but had halted in front of it, and had then been backed
out again. The marks were not very recent, however,
and at least one rain had fallen since they were
made.</p>
<p>Cray walked on to the rear gate and peered over.
There was a newly graded road beyond, and in its
surface were the marks of other tires—or, rather, the
marks of the same tires repeated several times, a number
of sets of them being more recent than those
in the yard. And all were made by tires of the sort
in common use on electric machines.</p>
<p>“Been here often,” Cray concluded. “Hasn’t been
in the yard but once, but has come as far as the gate on
a number of occasions. Seems to have been undecided
about something, or had cold feet. What’s
more, unless I’m ’way off the track, that machine has
been here not later than night before last, and those
freshest marks look suspiciously as if they were made
last night.”</p>
<p>He actually forgot Mrs. Simpson for the time being,
and, opening the gate, passed through. He had seen
something which interested him, the print of a rather
small shoe in the soft ground just beyond the gate,
where one would naturally have stood to open the
gate from the outside.</p>
<p><span class="pagenum"><SPAN name="Page_83" id="Page_83">[83]</SPAN></span></p>
<p>The detective took a steel tape line from his pocket,
and carefully measured the footprint. Incidentally, he
gave the tire marks a close examination.</p>
<p>Soon he straightened up and looked about him. In
doing so, he was more struck than ever with the isolation
of the Simpson house. The spot where they stood
was not overlooked by any other residence. There
was another house within two or three hundred yards,
to be sure, but it presented a blank wall on that side,
evidently being designed to stand close to another one,
which was yet to be built.</p>
<p>“Supposing the fellow had any motive to do it, he
could come here in a noiseless electric at the dead of
night, with lights turned off, and nobody would be
the wiser,” Cray told himself. “And he could reach
the hill here without passing through the center of
the village itself.”</p>
<p>At that point, however, he glanced up at the rear
of the Simpson house.</p>
<p>“How about his wife, though?” he went on to himself.
“She evidently isn’t wise to any such thing,
and yet there are plenty of windows here, at the rear—and
not very far from the garage, either.”</p>
<p>That brought him back, and he rather awkwardly
entered the yard, fearing that he might have betrayed
curiosity of an altogether too professional character.</p>
<p>“A fellow can’t help trying to act like a detective,
I guess, when he’s put on such a job like this,” he said,
with a sheepish grin. “I see right now that I’m not
in the same class with Nick Carter. Suppose I’ll
have to try to keep up the bluff just the same, and<span class="pagenum"><SPAN name="Page_84" id="Page_84">[84]</SPAN></span>
ask some more fool questions—if you are not ready to
throw me out.”</p>
<p>“Of course not, Mr. Jones,” the poor little woman
assured him. “I only wish——”</p>
<p>The detective nodded. “I wish, too, that I could
find him for you, Mrs. Simpson,” he said sincerely,
and added, under his breath, “and for you alone.”</p>
<p>“May be I will—who knows?” he went on, gazing
thoughtfully about. “By the way, where do you sleep,
if I may ask? At the back of the house?”</p>
