"I want to talk to you," went on Derek, "and who knows when I may have another opportunity? There is an idea going about that I murdered my wife—no, please don't interrupt. It is absurd, of course." He paused for a minute or two, then went on, speaking more deliberately. "In dealing with the police and Local Authorities here I have had to pretend to—well—a certain decency. I prefer not to pretend with you. I meant to marry money. I was on the lookout for money when I first met Ruth Van Aldin. She had the look of a slim Madonna about her, and I—well—I made all sorts of good resolutions—and was bitterly disillusioned. My wife was in love with another man when she married me. She never cared for me in the least. Oh, I am not complaining; the thing was a perfectly respectable bargain. She wanted Leconbury and I wanted money. The trouble arose simply through Ruth's American blood. Without caring a pin for me, she would have liked me to be continually dancing attendance. Time and again she as good as told me that she had bought me and that I belonged to her. The result was that I behaved abominably to her. My father-in-law will tell you that, and he is quite right. At the time of Ruth's death, I was faced with absolute disaster." He laughed suddenly. "One is faced with absolute disaster when one is up against a man like Rufus Van Aldin."
"And then?" asked Katherine in a low voice.
"And then," Derek shrugged his shoulders, "Ruth was murdered—very providentially."

"Bad luck?" said Katherine sharply.
He stared at her. "Why do you repeat it like that? What have you got in your mind?"
"I was thinking of things that people have said to me."
Derek grinned suddenly. "They will say a lot to you about me, my dear, and most of it will be true. Yes, and worse things too—things that I shall never tell you. I have been a gambler always—and I have taken some long odds. I shan't confess to you now or at any other time. The past is done with. There is one thing I do wish you to believe. I swear to you solemnly that I did not kill my wife."
He said the words earnestly enough, yet there was somehow a theatrical touch about them. He met her troubled gaze and went on:
