“You have seen something of Miss Grey, have you not?” inquired Poirot, innocently turning to the secretary.

“I⁠—yes; once or twice,” said Knighton.

He blushed slightly and Van Aldin exclaimed in surprise:

“Funny you never mentioned to me that you had seen her, Knighton.”

“I didn’t think you would be interested, sir.”

“I like that girl very much,” said Van Aldin.

“It is a thousand pities that she should have buried herself once more in St. Mary Mead,” said Poirot.

“It is very fine of her,” said Knighton hotly. “There are very few people who would bury themselves down there to look after a cantankerous old woman who has no earthly claim on her.”
