"From the report furnished to us at the Yard it seems that one day last August, while the gentleman in question was riding upon a trolley on the Cerro de Pasco railway, the conveyance was accidentally overturned into a river, and he was badly injured in the spine. A friend of his, a somewhat mysterious Englishman named Cane, brought him down to the hospital at Lima, and after two months there, he becoming convalescent, was conveyed for fresh air to Huacho, on the sea. Here he lived with Cane in a small bungalow in a somewhat retired spot, until on one night in February last year something occurred--but exactly what, nobody is able to tell. Sir Digby was found by his Peruvian servant dead from snake-bite. Cane evinced the greatest distress and horror until, of a sudden, a second man-servant declared that he had heard his master cry out in terror as he lay helpless in his bed. He heard him shriek: 'You--you blackguard, Cane--take the thing away! Ah! God! You've--you've killed me!' Cane denied it, and proved that he was at a friend's house playing cards at the hour when the servant heard his master shout for help. Next day, however, he disappeared. Our Consul in Lima took up the matter, and in due course a full report of the affair was forwarded to the Yard, together with a very detailed description of the man wanted. This we sent around the world, but up to to-day without result." "Then the man Cane was apparently responsible for the death of the invalid," I remarked. "I think so--without a doubt." "But who was the invalid? Was he the real Sir Digby?" "Aye, that's the question," said Edwards, thrusting his hands into his trouser pockets. For some moments we both sat staring blankly into the fire. "Among the papers sent to us," he said very slowly at last, "was this. Read it, and tell me your opinion." And then he took from his pocket-book and handed me a half-sheet of thin foreign notepaper, which had been closely written upon on both sides. It was apparently a sheet from a letter, for there was no beginning and no ending. The handwriting was educated, though small and crabbed, and the ink brown and half-faded, perhaps because of its exposure to a tropical climate. It had been written by a man, without a doubt. "That," said Edwards, "was found in a pocket-book belonging to Cane, which, in his hasty flight, he apparently forgot. According to our report the wallet was found concealed beneath the mattress of his bed, as though he feared lest anyone should read and learn what it contained. Read it, and tell me what you think." I took the sheet of thin paper in my fingers, and, crossing the room to a brighter light, managed to decipher the writing as follows:
