"It would have been useful too," I said, "if it turned out to be something merely futile."

"You're not going to hurt my Samuel, however futile it is," said Myra.
"Dahlia, how's Peter, and will you have some coffee?"

"Peter's lovely. You've had coffee, haven't you, Archie?"

"Better have some more," I suggested, "in case Simpson is merely soporific. We anticipate a slumbering audience, and Samuel explaining a new kind of googlie he's invented."

Entered Thomas lazily.

"Hallo," he said in his slow voice. "What's it all about?"

"It's a raid on the Begum's palace," explained Archie rapidly. "Dahlia decoys the Chief Mucilage; you, Thomas, drive the submarine; Myra has charge of the clockwork mouse, and we others hang about and sing. To say more at this stage would be to bring about a European conflict."

"Coffee, Thomas?" said Myra.

"I bet he's having us on," said Thomas gloomily, as he stirred his coffee.

There was a hurricane in the hall. Chairs were swept over; coats and hats fell to the ground; a high voice offered continuous apologies—and Simpson came in.
