“You're more likely to be in the dock,” said his sister unkindly.

“In that case,” replied Kenneth, finishing his whisky-and-soda, “I shall bring in the embezzlement-motif. Sauve qui peut.”

Mesurier thrust his hands into his pockets and forced his lips to smile. “I rather fancy a jury would see that occurrence in a more reasonable light,” he remarked. “I don't pretend that I was justified in doing what I did, but there's no question of - of theft. I've already paid back a great deal of what I borrowed.”

“The point is, Arnold didn't look at it in a reasonable light at all,” said Antonia.

You can't pinch a man's money, and then say, "Thank you for the loan" and pay it back in driblets. I don't in the least blame Arnold for cutting up rough, and, what's more, no jury would either. They'll see that Rudolph's got a motive for murder that makes mine look childish.”

“You saw Arnold Vereker after he was dead, didn't you?” said Giles.

There was a moment's silence. Violet gave a shiver, “You're making me feel sick. Do, do let's talk of something else!”
