“What is it?”

“Look!”

The chest was nearly empty, and there, reposing right at the bottom, was a magnificent black beard.

Ohó!” said Poirot. “Ohó!” He turned it over in his hands, examining it closely. “New,” he remarked. “Yes, quite new.”

After a moment’s hesitation, he replaced it in the chest, heaped all the other things on top of it as before, and made his way briskly downstairs. He went straight to the pantry, where we found Dorcas busily polishing her silver.

Poirot wished her good morning with Gallic politeness, and went on:

“We have been looking through that chest, Dorcas. I am much obliged to you for mentioning it. There is, indeed, a fine collection there. Are they often used, may I ask?”

“Well, sir, not very often nowadays, though from time to time we do have what the young gentlemen call ‘a dress-up night.’ And very funny it is sometimes, sir. Mr. Lawrence, he’s wonderful. Most comic! I shall never forget the night he came down as the Char of Persia, I think he called it—a sort of Eastern King it was. He had the big paper knife in his hand, and ‘Mind, Dorcas,’ he says, ‘you’ll have to be very respectful. This is my specially sharpened scimitar, and it’s off with your head if I’m at all displeased with you!’ Miss Cynthia, she was what they call an Apache, or some such name—a Frenchified sort of cut-throat, I take it to be. A real sight she looked. You’d never have believed a pretty young lady like that could have made herself into such a ruffian. Nobody would have known her.”

“These evenings must have been great fun,” said Poirot genially. “I suppose Mr. Lawrence wore that fine black beard in the chest upstairs, when he was Shah of Persia?”

“He did have a beard, sir,” replied Dorcas, smiling. “And well I know it, for he borrowed two skeins of my black wool to make it with! And I’m sure it looked wonderfully natural at a distance. I didn’t know as there was a beard up there at all. It must have been got quite lately, I think. There was a red wig, I know, but nothing else in the way of hair. Burnt corks they use mostly—though ‘tis messy getting it off again. Miss Cynthia was a nigger once, and, oh, the trouble she had.”
