Signor Malipizzo was doing a good deal. He meant to sift the thing to the bottom. His energy, hitherto simulated, was now set genuinely at work to discover indications of the murderer—indications of his missing friend. But Nepenthe is not a good place for finding corpses. The island is full of fathomless rents and fissures. A good many foreigners, especially such as were known to carry loose gold in their pockets, had been suspected of falling into them without leaving a trace behind. Yet a thorough search was instituted, for he knew that criminals were not always as clever as they thought themselves; some insignificant relic might turn up—a shred of clothing or so forth. Such things were occasionally picked up on Nepenthe; nobody knew to whom they belonged. The Cave of Mercury, on being searched, yielded nothing but a trouser button, apparently of English manufacture. Enquiries were also made as to when the ill-starred gentleman had last been seen, and where. Finally, the judge drew up a list, a fairly long list, of all the suspicious characters on the place with a view to placing them under lock and key, in expectation of further developments. Such was the customary procedure; one must assume the worst. If innocent, they might of course regain their liberty in a year or two.
It stands to reason that a good many people had noticed Muhlen on the morning of his disappearance. One cannot walk about Nepenthe at that hour of the day without being seen, and Muhlen was sufficiently conspicuous. But everyone knew what was in store for him if he admitted such a fact, to wit, an application of paragraph 43 of the 92nd section of the Code of Criminal Procedure, according to which any and every witness of this kind is liable to be segregated from his family and kept under arrest for an indefinite length of time, pending the instruction of a trial which might take half a century. Nobody, therefore, was fool enough to admit having encountered him—nobody save a half-witted youth who fatuously confided to a policeman that the had met the gentleman somewhere in the neighbourhood of the bibliographer's villa about the hour of midday. Under ordinary circumstances Signor Malipizzo would have been delighted to lay sacrilegious hands on Mr. Eames, whose Olympic aloofness had always annoyed him and against whom a case could now be got up, on the strength of these indications. Somewhere in the neighbourhood of the villa—that was quite sufficient to warrant an arrest.
The boy in question happened to be a relation of his arch-enemy, the parish priest. Better still. Chuckling at the happy coincidence, he forgot all about Mr. Eames, and gave orders for the other to be conveyed to the guard-house, searched, and interrogated, arguing plausibly that a person of his mental instability would be sure to give himself away by some stupid remark.
Things turned out better than he had dared to hope. Under the prisoner's clothing was discovered a gold coin of foreign nationality attached, by a piece of string, round his neck. For all one knew, it might have been Muhlen's. The interrogating carbineer who is invested, during such preliminary enquiries, with quasi-judicial functions—being permitted to assume the role of prosecuting or defending counsel, or to remain sternly unbiased, as he feels inclined—desired to learn how he had come by this jewel.
He received it long ago from his mother, he said, as a talisman against the moonsickness which had tormented him in childhood. Replying, in stammering and dazed fashion, to further questions, he gave it to be understood that nobody had ever set eyes on the coin in question; he was afraid of showing it, lest someone should take it from him by force. He loved the coin. He got it from his mother.
"Ah!" said the friendly policeman. "And your mother, now—could she perhaps tell us when she gave it to you?"
"My mother is in Paradise."
"Dead, is she? H'm. That looks queer, my young friend. Very fishy. You should be more careful in little things like that. She ought to have been kept alive, you know. Anybody can say they had gold coins given them by dead mothers, don't you see? Rather a thin trick. Can't you suggest something better? Cheer up, boy! You needn't tremble all over. Look, I am writing it down, and you must put your name to it afterwards. Think—little. A living uncle, for instance—if he came into Court and testified that he had given you the coin, why, it might make all the difference and get you out of a nasty scrape. Surely you've got an uncle or something? How about His Reverence the PARROCO? Couldn't he swear—?"
"My mother is in Paradise."
"In Paradise, is she? That's where you ought to be, my son. Just sign this declaration, please. Then perhaps you will meet your mother sooner than you expect. Can't read or write? Well, put your cross to it and may the Madonna help you! For I can't. I've done my best to be impartial, but God alone can steer a fool. He makes a specialty of it, they tell me. If so, you've got a sporting chance…."
