To me, it was a curious circumstance that Cardew, when he heard the shriek, had not attempted to investigate its cause. True, he had listened, and the cry was not repeated. I should have regarded his apathy as suspicious if I myself had not more than once, when dreaming, awakened suddenly, believing that I had heard a cry of distress. The shriek of terror--nay, of horror, Cardew described it--was, in itself, a most peculiar circumstance. There is a distinct difference between a cry of pain and a shriek of horror. No; I felt certain that the medical men had not sufficiently considered that very singular point. But when I tried to argue with the Captain, he merely declared that the cause of the shriek would never be explained. Perhaps it was the sudden knowledge that he was dying that had terrified him. I intended, however, to seek further explanation. It was ever upon my mind that the man who had died so mysteriously intended to visit me on Sunday, and to reveal to me something--something concerning Harvey Shaw. Shaw was a guest that evening, but it was proved beyond the shadow of a doubt that he had left the house two and a half hours before, accompanied by Asta. It was therefore my intention at once to satisfy myself whether Shaw could have returned, unknown to the girl, and re-visited Titmarsh Court. I confess openly and frankly that I suspected a crime. Hence, I spared no effort in thoroughly investigating the curious circumstances--in doing work which the police would have done had not the declarations of the two doctors been so very positive and emphatic. I saw the body of my friend lying in a darkened bedroom upstairs, and covered with a sheet. I did not remove the shroud. I was too horrified. A post-mortem had been made, and the corpse was waiting for the arrival of the coffin. What had the dead man intended to reveal to me? He had evidently discovered something detrimental to Shaw. Of that I felt assured, for had he not admitted as much? "Did poor Guy appear his usual self before the affair?" I asked Cardew some half-hour later, as we again stood together in the long sombre room wherein he had died. The atmosphere was heavy with the oppressive scent of the roses, and about the silent apartment there seemed an air of mystery. "Well, to tell the truth, I did not notice anything unusual in his manner at the time. But since--now that I have reflected--I recollect that he seemed extremely anxious concerning Shaw's daughter--as though he were apprehensive of something, and was in despair." At that moment the Captain was called out by one of the servants, who told him that the police superintendent from Northampton would like to see him. Therefore I was left alone in the room, and was thus afforded opportunity to examine it.
