Wimsey sighed.
"There's something in what you say," he admitted. "Still, you never know. Now then, is there any name we've thought of which appears in all three columns of our list?"
"No, not one. But several appear in two."
"We'd better start on those, then. Miss Dorland is the most obvious, naturally, and after her, George, don't you think?"
"Yes. I'll have a round-up among all the chemists who may possibly have supplied her with the digitalin. Who's her family doctor?"
"Dunno. That's your pigeon. By the way, I'm supposed to be meeting the girl at a cocoa-party or something of the sort to-morrow. Don't pinch her before then if you can help it."
"No; but it looks to me as though we might need to put a few questions. And I'd like to have a look round Lady Dormer's house."
"For heaven's sake, don't be flat-footed about it, Charles. Use tact."
"You can trust your father. And, I say, you might take me down to the Bellona in a tactful way. I'd like to ask a question or two there."
Wimsey groaned.
