I should never forgive him if he did," said her husband, piously.

He poured himself out another glass of beer and resumed his supper with
relish. Conversation turned on the weather, and from that to the price
of potatoes. Frantic efforts on the part of the prisoner to join in the
conversation and give it a more personal turn were disregarded. Finally
he began to kick with monotonous persistency on the door.

"Stop it!" shouted Mr. Cooper.

"I won't," said Mr. Simpson.

The noise became unendurable. Mr. Cooper, who had just lit his pipe,
laid it on the table and looked round at his companions.

"He'll have the door down soon," he said, rising. "Halloa, there!"

"Halloa!" said the other.

"You say you're Bill Simpson," said Mr. Cooper, holding up a forefinger
at Mrs. Simpson, who was about to interrupt. "If you are, tell us
something you know that only you could know; something we know, so as to

philosophically. "Carry your mind back ten years, Bob Cooper--"

"Look here!" said Mr. Cooper, turning round with a ghastly smile.
"We'd better get off home, Mary. I don't like interfering in other
people's concerns. Never did."

"You stay where you are," said his wife.

"Ten years," repeated the voice behind the door. "There was a new
barmaid at the Crown, and one night you----"

"If I listen to any more of this nonsense I shall burst," remarked Mr.
Cooper, plaintively.

"Go on," prompted Mrs. Cooper, grimly. "One night----"

"Never mind," said Mr. Simpson. "It doesn't matter. But does he
identify me? Because if not I've got a lot more things I can try."
