"What, however, are the facts?" it was demanding, with the causticity of baffled helplessness. "I am assured that there is no other key in existence; yet my safe has been unlocked. I am given to understand that without the password it would be impossible for an unauthorized person to tamper with my property. My password, deliberately chosen, is 'anthropophaginian,' sir. Is it one that is familiarly on the lips of the criminal classes? But my safe is empty! What is the explanation? Who are the guilty persons? What is being done? Where are the police?" "If you consider that the proper course to adopt is to stand on the doorstep and beckon in the first constable who happens to pass, permit me to say, sir, that I differ from you," retorted the distracted manager. "You may rely on everything possible being done to clear up the mystery. As I told you, I have already telephoned for a capable private detective and for one of my directors." "But that is not enough," insisted the professor angrily. "Will one mere private detective restore my £6000 Japanese 4-1/2 per cent. bearer bonds? Is the return of my irreplaceable notes on 'Polyphyletic Bridal Customs among the mid-Pleistocene Cave Men' to depend on a solitary director? I demand that the police shall be called in--as many as are available. Let Scotland Yard be set in motion. A searching inquiry must be made. I have only been a user of your precious establishment for six months, and this is the result." "There you hold the key of the mystery, Professor Bulge," interposed Carrados quietly. "Who is this, sir?" demanded the exasperated professor at large. "Permit me," explained Mr. Carlyle, with bland assurance. "I am Louis Carlyle, of Bampton Street. This gentleman is Mr. Max Carrados, the eminent amateur specialist in crime." "I shall be thankful for any assistance towards elucidating this appalling business," condescended the professor sonorously. "Let me put you in possession of the facts--" "Perhaps if we went into your room," suggested Carrados to the manager, "we should be less liable to interruption." "Quite so; quite so," boomed the professor, accepting the proposal on everyone else's behalf. "The facts, sir, are these: I am the unfortunate possessor of a safe here, in which, a few months ago, I deposited--among less important matter--sixty bearer bonds of the Japanese Imperial Loan--the bulk of my small fortune--and the manuscript of an important projected work on 'Polyphyletic Bridal Customs among the mid-Pleistocene Cave Men.' Today I came to detach the coupons which fall due on the fifteenth; to pay them into my bank a week in advance, in accordance with my custom. What do I find? I find the safe locked and apparently intact, as when I last saw it a month ago. But it is far from being intact, sir! It has been opened, ransacked, cleared out! Not a single bond, not a scrap of paper remains."
