«Thank you, my lord. I may say that I'm very grateful to you — this case was turning out a pretty bad egg for me. If I was rude to your lordship —»
«Oh, it's all right, Inspector,» said Lord Peter, hastily. «I don't see how you could possibly have worked it out. I had the good luck to know something about it from other sources.»
«That's what Freke says.» Already the great surgeon was a common criminal in the inspector's eyes — a mere surname. «He was writing a full confession when we got hold of him, addressed to your lordship. The police will have to have it, of course, but seeing it's written for you, I brought it along for you to see first. Here it is.»
He handed Lord Peter a bulky document.
«Thanks,» said Peter. «Like to hear it, Charles?»
«Rather.»
Accordingly Lord Peter read it aloud.
XIII
Dear Lord Peter — When I was a young man I used to play chess with an old friend of my father's. He was a very bad, and a very slow, player, and he could never see when a checkmate was inevitable, but insisted on playing every move out. I never had any patience with that kind of attitude, and I will freely admit now that the game is yours. I must either stay at home and be hanged or escape abroad and live in an idle and insecure obscurity. I prefer to acknowledge defeat.
If you have read my book on «Criminal Lunacy,» you will remember that I wrote: «In the majority of cases, the criminal betrays himself by some abnormality attendant upon this pathological condition of the nervous tissues. His mental instability shows itself in various forms: an overweening vanity, leading him to brag of his achievement; a disproportionate sense of the importance of the offence, resulting from the hallucination of religion, and driving him to confession; egomania, producing the sense of horror or conviction of sin, and driving him to headlong flight without covering his tracks; a reckless confidence, resulting in the neglect of the most ordinary precautions, as in the case of Henry Wainwright, who left a boy in charge of the murdered woman's remains while he went to call a cab, or on the other hand, a nervous distrust of apperceptions in the past, causing him to revisit the scene of the crime to assure himself that all traces have been as safely removed as his own judgment knows them to be. I will not hesitate to assert that a perfectly sane man, not intimidated by religious or other delusions, could always render himself perfectly secure from detection, provided, that is, that the crime were sufficiently premeditated and that he were not pressed for time or thrown out in his calculations by purely fortuitous coincidence.»
