Giles made no reply to this, but when the gloves were at last on, he moved in his leisurely way towards the door, and opened it for Violet to pass out.

“Well, Tony,” she said, tucking her bag under her arm, “if I've said anything I shouldn't, I'm sorry, but this thing is getting absolutely on my nerves. You had better come along, too, Leslie; Tony wants to talk to her cousin.”

Leslie said stiffly: “Of course. But please don't wait for me. I'm not going your way.”

“Oh, just as you like, my dear,” Violet replied, shrugging. She walked to the door, but paused there as a thought occurred to her. “I don't know if you've any of you realised it, but there's one person we've left out of our calculations. Where was Mr Mesurier last night?”

“Old Boy's Dinner,” said Antonia briefly.

“Really? But it wouldn't have been impossible for him to have left early, I suppose.”

“I do wish you'd stop making fatuous suggestions,” Antonia sighed. “What on earth should induce Rudolph to murder Roger?”

“You needn't be so high-and-mighty, my dear. I can think of one very good reason. We all know that he said he meant to murder Arnold Vereker because of his - well, really, I must call it pilfering. Now, if Roger knew about that, and meant to prosecute -”

“You're missing on all your cylinders,” interrupted Antonia “Roger knew, and he told Rudolph he wouldn't do anything about it. And if you don't believe me, I wrote a letter to Roger, thanking him. Can't you think of somebody else to suspect?”

Violet gave a little laugh. “Oh, nothing I say will meet with approval in this house! I'm well aware of that! Goodbye, Mr Carrington. No, please don't bother to see me out. I know my way.”
