Hastings led the way familiarly past the girl sitting at a desk in the outside office and we soon found ourselves in the section that was set apart for the accounting department, over which Randall had charge.

It seemed that the lawyer was well acquainted with the cashier as he introduced him to us, and we noted that Randall was a man approaching middle age, at least outwardly, with that solid appearance that seems to come to men who deal with numbers and handle large sums of money.

While we talked I looked about curiously. Randall had an inner office, though in the outer office stood the huge safe which was evidently the one which had been rifled.

The cashier himself seemed to have lost, for the time, some of his customary poise. Trying to make him out, I fancied that he was nearly frantic with fear lest he might be suspected, not so much, perhaps, of having had anything to do with the loss of the telautomaton as of being remiss in his duties, which included the guardianship of the safe.

The very anxiety of the man seemed to be a pretty good guarantee of his honesty. There could be no doubt of how deeply he felt the loss, not only because it was of such vital importance, but from the mere fact that it might reflect on his own management of his department.

“It seems almost incredible,” Randall exclaimed as we stood talking. “The most careful search has failed to reveal any clue that would show even how access to the office was gained. Not a lock on any of the doors has been tampered with, not a scratch indicates the use of a jimmy on them or on the windows. In fact, entrance by the windows at such a height above the surrounding buildings is almost beyond the range of possibility as well as probability. How could it have been accomplished? I am forced to come back to the explanation that the outer office doors had been opened by a key!”

“There were keys—in the hands of several people, I suppose?” inquired Kennedy.

“Oh yes! There are in every large office like this,” hastened Randall.

“Mr. Maddox had a key, of course?”

“Yes.”
