The bed--a large wooden one, but not a fourposter--stood on the left-hand side of the room from the entrance, with the head against the wall nearest the outside passage, and the foot partly in line with the open window, which was about eight feet away from it. The door when pushed back swung just clear of a small bedroom table beside the bed, on which the reading lamp stood, with a book beside it. The other side of the bed was close to the wall which divided the room from the next bedroom, so that there was a large clear space on the outside, between the bed and the door. The gas fitting, which was suspended from the ceiling in this open space, hung rather low, the bottom of the globe being not more than six feet from the floor. The globe was cracked, and the incandescent burner was broken. The murdered man had been laid in the middle of the bed, and covered with a sheet. Superintendent Galloway quietly drew the sheet away, revealing the massive white head and clear-cut death mask of a man of sixty or sixty-five; a fine powerful face, benign in expression, with a chin and mouth of marked character and individuality. But the distorted contour of the half-open mouth, and the almost piteous expression of the unclosed sightless eyes, seemed to beseech the assistance of those who now bent over him, revealing only too clearly that death had come suddenly and unexpectedly. "He was a great archaeologist--one of the greatest in England," said Mr. Cromering gently, with something of a tremor in his voice, as he gazed down at the dead man's face. "To think that such a man should have been struck down by an assassin's blow. What a loss!" "Let us see how he was murdered," said the more practical Galloway, who was standing beside his superior officer. He drew off the covering sheet as he spoke, and dropped it lightly on the floor. The body thus revealed was that of a slightly built man of medium height. It was clad in a flannel sleeping suit, spattered with mud and clay, and oozing with water. The arms were inclining outwards from the body, and the legs were doubled up. There were a few spots of blood on the left breast, and immediately beneath, almost on the left side, just visible in the stripe of the pyjama jacket, was the blow which had caused death--a small orifice like a knife cut, just over the heart. "It is a very small wound to have killed so strong a man," said Mr. Cromering. "There is hardly any blood." Sir Henry examined the wound closely. "The blow was struck with great force, and penetrated the heart. The weapon used--a small, thin, steel instrument--and internal bleeding, account for the small external flow." "What do you mean by a thin, steel instrument?" asked Superintendent Galloway. "Would an ordinary table-knife answer that description?"
