“Of course I was wearing them.  There was nothing finer here to-night—­that I saw.”

“You hadn’t got them on when you came in here before.”

“Hadn’t I?” said Eve, thoughtful.

“No, you hadn’t.”

“Then why didn’t you tell me?” Eve demanded suddenly, almost fiercely, through her tears, withdrawing her shoulders from his hands.

“Well,” said Mr. Prohack.  “I thought you’d know what you’d got on, or what you hadn’t got on.”

“I think you might have told me.  If you had perhaps the—­”

Mr. Prohack put his hand over her mouth.

“Stop,” said he.  “My sweet child, I can save you a lot of trouble.  It’s all my fault.  If I hadn’t been a miracle of stupidity the necklace would never have disappeared.  This point being agreed to, let us go on to the next.  When did you find out your sad loss?”

“It was Miss Winstock who asked me what I’d done with my necklace.  I put my hand to my throat, and it was gone.  It must have come undone.”

“Didn’t you say to me a fortnight or so ago that the little safety-chain had gone wrong?”

“Did I?” said Eve, innocently.

“Did you have the safety-chain repaired?”

“I was going to have it done to-morrow.  You see, if I’d sent it to be done to-day, then I couldn’t have worn the necklace to-night, could I?”

“Very true,” Mr. Prohack concurred.

“But who could have taken it?”

“Ah!  Are you sure that it isn’t lying on the floor somewhere?”

“Every place where I’ve been has been searched—­thoroughly.  It’s quite certain that it must have been picked up and pocketed.”

“Then by a man, seeing that women have no pockets—­except their husbands’.  I’m beginning to feel quite like a detective already.  By the way, lady, the notion of giving a reception in a house like this without a detective disguised as a guest was rather grotesque.”

“But of course I had detectives!” Eve burst out.  “I had two private ones.  I thought one ought to be enough, but as soon as the agents saw the inventory of knicknacks and things, they advised me to have two men.  One of them’s here still.  In fact he’s waiting to see you.  The Scotland Yard people are very annoying.  They’ve refused to do anything until morning.”

That Eve should have engaged detectives was something of a blow to the masculine superiority of Mr. Prohack.  However, he kept himself in countenance by convincing himself in secret that she had not thought of the idea; the idea must have been given to her by another person—­probably Mimi, who nevertheless was also a woman.

“And do you seriously expect me to interview a detective in the middle of the night?” demanded Mr. Prohack.

“He said he should like to see you.  But of course if you don’t feel equal to it, my poor boy, I’ll tell him so.”

“What does he want to see me for?  I’ve nothing to do with it, and I know nothing.”
