“You remember my speaking of my friend Poirot? The Belgian who is here? He has been a most famous detective.”

“Yes.”

“I want you to let me call him in—to investigate this matter.”

“What—now? Before the post-mortem?”

“Yes, time is an advantage if—if—there has been foul play.”

“Rubbish!” cried Lawrence angrily. “In my opinion the whole thing is a mare’s nest of Bauerstein’s! Wilkins hadn’t an idea of such a thing, until Bauerstein put it into his head. But, like all specialists, Bauerstein’s got a bee in his bonnet. Poisons are his hobby, so of course he sees them everywhere.”

I confess that I was surprised by Lawrence’s attitude. He was so seldom vehement about anything.

John hesitated.

“I can’t feel as you do, Lawrence,” he said at last. “I’m inclined to give Hastings a free hand, though I should prefer to wait a bit. We don’t want any unnecessary scandal.”

“No, no,” I cried eagerly, “you need have no fear of that. Poirot is discretion itself.”
