wire mattress. She must have stolen it and hidden it there before the chambermaid arrived on the scene."
"You permit, madame?" said Poirot gently. He took the necklace from her and examined it closely; then handed it back with a bow.
"I'm afraid, madam, you'll have to hand it over to us for the time being," said the inspector. "We shall want it for the charge. But it shall be returned to you as soon as possible."
Mr. Opalsen frowned.
"Is that necessary?"
"I'm afraid so, sir. Just a formality."
"Oh, let him take it, Ed!" cried his wife. "I'd feel safer if he did. I shouldn't sleep a wink thinking some one else might try and get hold of it. That wretched girl! And I would never have believed it of her."
"There, there, my dear, don't take on so."

Once outside, however, he hesitated, and then, much to my surprise, he remarked:
"I should rather like to see the room next door."
