“No, I'm afraid I didn't My sister might know. She went up at the same time.”

“Yes, I should like to have a talk with Miss—Miss Stella Matthews,” nodded Hannasyde, consulting his notebook. “And with Mrs Matthews too, if you please.”

“My mother doesn't get up till after breakfast, but I'll go and tell her,” volunteered Guy, and left the room.

Mrs Matthews was doing her hair at the dressing-table when her son knocked on the door. She smiled at him as he came in, and said: “Well, darling, not gone off to work yet?”

“No, and a darned good job too!” said Guy. “Haven't you heard? There's a chap from Scotland Yard downstairs, cross-examining everybody!”

Mrs Matthews' comb was stayed in mid-air; in the mirror her eyes met Guy's for one startled moment. Then she put the comb down, and turned in her chair to face him. “Scotland Yard,” she repeated. “That means he was poisoned.”

“Yes, something to do with nicotine. I never heard of poisoning anybody with nicotine myself but that's what Fielding said. The Superintendent's interviewing Aunt Harriet now, and then he wants to see you and Stella. He's already asked Aunt Harriet and me a whole lot of questions. Aunt was scared out of her life at first, but personally I found it rather amusing.”

“What did your aunt say?” asked Mrs Matthews quickly.

“Oh, she drivelled on in her usual style! Mostly irrelevant. Except that she would insist on stressing the fact that it was I who poured out uncle's drink for him on the night he died.” He gave a little laugh. “Actually it wouldn't be a bad plan if someone tipped her the wink not to talk so much. Given time she'll tell the police all the family details, down to what uncle was like in the cradle.”

Mrs Matthews began to put up her hair. “I'll go down at once. Run along while I finish dressing, dear. Oh, and Guy!—Find Stella, and tell her I want her, will you? And just remember, darling, that the less you say the better. It isn't that there's anything to conceal, but you and Stella are inclined to let your tongues run away with you, and you very often give a totally wrong impression to people. I want you for all our sakes to be careful what you say.”
