"Eighteen months ago 'Harry the Actor' successfully looted the office safe of M'Kenkie, J.F. Higgs & Co., of Cleveland, Ohio. He had just married a smart but very facile third-rate vaudeville actress—English by origin—and wanted money for the honeymoon. He got about five hundred pounds, and with that they came to Europe and stayed in London for some months. That period is marked by the Congreave Square post office burglary, you may remember. While studying such of the British institutions as most appealed to him, the 'Actor's' attention became fixed on this safe-deposit. Possibly the implied challenge contained in its telegraphic address grew on him until it became a point of professional honour with him to despoil it; at all events he was presumedly attracted by an undertaking that promised not only glory but very solid profit. The first part of the plot was, to the most skilful criminal 'impersonator' in the States, mere skittles. Spreading over those months he appeared at 'The Safe' in twelve different characters and rented twelve safes of different sizes. At the same time he made a thorough study of the methods of the place. As soon as possible he got the keys back again into legitimate use, having made duplicates for his own private ends, of course. Five he seems to have returned during his first stay; one was received later, with profuse apologies, by registered post; one was returned through a leading Berlin bank. Six months ago he made a flying visit here, purely to work off two more. One he kept from first to last, and the remaining couple he got in at the beginning of his second long residence here, three or four months ago.
"This brings us to the serious part of the cool enterprise. He had funds from the Atlantic and South-Central Mail-car coup when he arrived here last April. He appears to have set up three establishments; a home, in the guise of an elderly scholar with a young wife, which, of course, was next door to our friend the manager; an observation point, over which he plastered the inscription 'Rub in Rubbo for Everything' as a reason for being; and, somewhere else, a dressing-room with essential conditions of two doors into different streets.
"About six weeks ago he entered the last stage. Mrs. Harry, with quite ridiculous ease, got photographs of the necessary page or two of the record-book. I don't doubt that for weeks before then everyone who entered the place had been observed, but the photographs linked them up with the actual men into whose hands the 'Actor's' old keys had passed—gave their names and addresses, the numbers of their safes, their passwords and signatures. The rest was easy."
"Yes, by Jupiter; mere play for a man like that," agreed Mr. Carlyle, with professional admiration. "He could contrive a dozen different occasions for studying the voice and manner and appearance of his victims. How much has he cleared?"
"We can only speculate as yet. I have put my hand on seven doubtful callers on Monday and Tuesday last. Two others he had ignored for some reason; the remaining two safes had not been allotted. There is one point that raises an interesting speculation."
"What is that, Max?"
"The 'Actor' has one associate, a man known as 'Billy the Fondant,' but beyond that—with the exception of his wife, of course—he does not usually trust anyone. It is plain, however, that at least seven men must latterly have been kept under close observation. It has occurred to me—"
"Yes, Max?"
"I have wondered whether Harry has enlisted the innocent services of one or other of our private inquiry offices."
"Scarcely," smiled the professional. "It would hardly pass muster."
