"We telephoned for the police and a doctor, and I spent the time until they came in a thorough examination of the room. The French-windows had been securely bolted top and bottom from within, by means of a central handle. All the panes of glass were intact, with the exception of that we had broken. The door had been locked on the inside, and the key was in position. It was unlocked by Peters when he went into the hall to telephone. It has a strong mortice-lock and the key did not protrude through to the outer side, so that there was no chance of manipulating the lock from without. In the fireplace there was an electric stove, and from the shower of soot that fell when I raised the trap, it was clear that this had not been touched for some weeks at least.
"The doctor was the first to arrive. At my urgent request he refrained from touching the body. He said death had taken place from seven to ten hours previously as the result of the bullet wound in the temple. He had scarcely finished his examination when an inspector of police, who had motored over from Lewes, joined us.
"It took him very few minutes to decide that poor Challoner had shot himself. In this he was confirmed by the doctor. Still, I insisted that the body should not be removed."
"Why did you do that, Chief?" enquired Malcolm Sage, who had discarded the paper-knife and was now busy drawing geometrical figures with the thumb-nail of his right hand upon the blotting pad before him.
"Because I was not satisfied," was the reply. "There was absolutely no motive for suicide. Challoner was in good health and, if I know anything about men, determined to live as long as the gods give."
Again Malcolm Sage nodded his head meditatively.
"The jumping to hasty conclusions," he remarked, "has saved many a man his neck. Whom did you leave in charge?" he queried.
"The inspector. I locked the door; here is the key," he said, producing it from his jacket pocket. "I told him to allow no one into the room."
"Why were you there?" Malcolm Sage suddenly looked up, flashing that keen, steely look through his gold-rimmed spectacles that many men had found so disconcerting. "Ordinary visit?" he queried.
"No." Sir James paused, apparently deliberating something in his own mind. He was well acquainted with Malcolm Sage's habit of asking apparently irrelevant questions.
