"As to Garcia," said Gregson, "that is easily answered. He was found dead this morning upon Oxshott Common, nearly a mile from his home. His head had been smashed to pulp by heavy blows of a sandbag or some such instrument, which had crushed rather than wounded. It is a lonely corner, and there is no house within a quarter of a mile of the spot. He had apparently been struck down first from behind, but his assailant had gone on beating him long after he was dead. It was a most furious assault. There are no footsteps nor any clue to the criminals." "Robbed?" "No, there was no attempt at robbery." "This is very painful--very painful and terrible," said Mr. Scott Eccles in a querulous voice, "but it is really uncommonly hard on me. I had nothing to do with my host going off upon a nocturnal excursion and meeting so sad an end. How do I come to be mixed up with the case?" "Very simply, sir," Inspector Baynes answered. "The only document found in the pocket of the deceased was a letter from you saying that you would be with him on the night of his death. It was the envelope of this letter which gave us the dead man's name and address. It was after nine this morning when we reached his house and found neither you nor anyone else inside it. I wired to Mr. Gregson to run you down in London while I examined Wisteria Lodge. Then I came into town, joined Mr. Gregson, and here we are." "I think now," said Gregson, rising, "we had best put this matter into an official shape. You will come round with us to the station, Mr. Scott Eccles, and let us have your statement in writing." "Certainly, I will come at once. But I retain your services, Mr. Holmes. I desire you to spare no expense and no pains to get at the truth." My friend turned to the country inspector. "I suppose that you have no objection to my collaborating with you, Mr. Baynes?" "Highly honoured, sir, I am sure." "You appear to have been very prompt and businesslike in all that you have done. Was there any clue, may I ask, as to the exact hour that the man met his death?" "He had been there since one o'clock. There was rain about that time, and his death had certainly been before the rain." "But that is perfectly impossible, Mr. Baynes," cried our client. "His voice is unmistakable. I could swear to it that it was he who addressed me in my bedroom at that very hour." "Remarkable, but by no means impossible," said Holmes, smiling. "You have a clue?" asked Gregson. "On the face of it the case is not a very complex one, though it certainly presents some novel and interesting features. A further knowledge of facts is necessary before I would venture to give a final and definite opinion. By the way, Mr. Baynes, did you find anything remarkable besides this note in your examination of the house?" The detective looked at my friend in a singular way.
