Marion Harvey, The Mystery of the Hidden Room
“ There is no such thing as an infallible criminal and a perfect crime. You may get away once, or perhaps a score of times, but in the end your weakness trips you and you fall into the hands of the authorities. In your case the thing that tripped you and delivered you to us was—love for a woman. A dangerous game to play, the woman game, Mr. Cunningham, but love knows no reason. You were so desperately infatuated with Cora Manning that the thought of going away and leaving her to a more successful rival was agony to you, and so you remained to persuade her to go with you. ”
