face that was extraordinary—a curious mingling of terror and agitation.
“Look, Poirot!” I said.
He leant forward.
“Tiens!” he said. “It is Mr. Mace, from the chemist’s shop. He is coming here.”
The young man came to a halt before Leastways Cottage, and, after hesitating a moment, pounded vigorously at the door.
“A little minute,” cried Poirot from the window. “I come.”
Motioning to me to follow him, he ran swiftly down the stairs and opened the door. Mr. Mace began at once.
“Oh, Mr. Poirot,
you ever known a chemist to send out a box like that, without his printed name?”
“No, I can’t say that I have.”
I was becoming quite excited, but Poirot damped my ardour by remarking:
“Yet the explanation is quite simple. So do not intrigue yourself, my friend.”
An audible creaking proclaimed the approach of Annie, so I had no time to reply.
