it to-morrow. We'll have it copied and
see if we can trace the subject of it. That might tell us something."

The following morning Phil was at Police Headquarters to pick up
further information, and to get a copy of the girl's photograph. Like
the police, he could not keep his mind off the idea that there was
some association between the crooked engineer and the disappearance of
the safes. It seemed to fit too well. The scientific nature of the
phenomena, Tony Costello's well known reputation for scientific
brilliance, and his recent affluence; what else could it mean? In some
way, Tony was getting at these safes. But how? And how prove it? Most
exhaustive searches failed to reveal any traces of the safes anywhere.
If any fragment of one of them had appeared in New York or San
Francisco, the news would have come at once, such was the sensation
all over the country that the series of disappearances had caused.
Tony's calm insolence during the raid, his attitude of waiting
patiently till the police should have had their fun and have it over
with so that he might be left at peace again, showed that he must be
guilty, for anyone else would have protested and felt deeply injured
and insulted. He seemed to be enjoying their discomfiture, and
absolutely confident of his own safety.

"There's got to be some way of getting him," Phil mused; and he mused
almost absent-mindedly, for he was gazing at the photograph of the
girl. For many minutes he looked at it, and then put it silently into
his pocket.

Five o'clock in the evening of that same day came the news of another
safe disappearance. Phil got his tip over the phone, and in fifteen
minutes was at the scene. It was too much like the others to go into
detail about; a six-foot portable safe had suddenly disappeared right
in front of the eyes of the office staff of The Epicure, a huge
restaurant and cafeteria that fed five thousand people three times a
day. In its place stood a ragged, rusty old Ford coupe body. He went
away from there, shaking his head.

Then suddenly in the midst of his dinner, he jumped up, and ran. An
idea had leaped into his head.

"Right after one of these things pops is the time to take a peek at
Tony," he said to himself, and immediately he was on the way.

But how to get his peep was not so easy a problem. When he alighted
from his cab a block away from Tony's
