"What." ejaculated Poulton, stiffening suddenly, in a way which made Inspector Grant think that the news camee as a shock to him, but which only caused his superior, one of the pillars of an Amateur Dramatic Society, to consider that the exclamation had been wellrehearsed.

"Yes, sir," he said phlegmatically.

"Good God!" Poulton paused. His eyes, under their level brows, lifted to the Chief Inspector's face. "I see. I can only tell you that when I left Mrs. Haddington she was alive, standing before the electric fire in her boudoir. She had just rung the bell, to summon her butler to show me out."

"Did you wait for the butler to appear, sir?"

"No. I took my leave of Mrs. Haddington, and left the room. The butler reached the hall as I was coming down the half-flight of stairs from Mrs. Haddington's sittingroom."

"And what, sir, was your reason for paying this call?"

Silence followed this question. Poulton was frowningly studying his finger-tips. After a moment he again looked up. "Yes, I see. You are bound to ask me that. I shall make no secret of the fact that my call was not of a friendly nature. Mrs. Haddington had been ringing up my house to ask for news of my wife: I went to Charles Street to inform her that my wife was unwell, and that it was my fixed intention to put an end to the intimacy that had hitherto flourished between them."

"Yes, sir? And why was that your fixed intention?"

"I did not care for the connaissance."

"That, sir, is not quite a good enough answer."
