“Some clean, some dirty,” Reggie repeated. “He got the dirty ones from the pawnbroker. Where did he get the clean ones? Still several unknown quantities in the equation.”

“How’s that, sir?” said Inspector Oxtoby.

“Well, there’s the body, for instance,” said Reggie mildly. “We lack the body. You know, I think we might ask Miss Darcourt to say a few words. Send a man up in a car to tell her she’s wanted at the police-station, because her chauffeur has been arrested. I should think she’ll come.”

“That’s the stuff!” Inspector Oxtoby chuckled and set about it.

“You always had a notion she knew something, sir,” said Bell reverently.

“I wonder,” Reggie murmured.

She did come. The little room seemed suddenly crowded, so large was the gold pattern on her black cloak, so complex her sinuous movements, as she glided in and sat down. She smiled at them, and certainly she had been handsome. From a white face dark eyes glittered, very big eyes, all pupil. “Oh, my aunt,” said Reggie to himself, “drugged.”

“Miss Rose Darcourt?” Inspector Oxtoby’s pen scratched. “Thank you, madam. Your chauffeur Albert Edward Loveday (that’s right?) has been arrested loitering about Miss Sheridan’s house. He was found in possession of Miss Sheridan’s gold cigarette-case. Can you explain that?”

“I? Why should I explain it? I know nothing about it.”

“The man is in your service, madam.”
