"Have a good look at it," he said, almost forcing it into the Frenchman's hand. "There's a safe in the wall of this room, made by my dead father-in-law, to keep such things as he didn't care to send to the bank. My wife and I are the only people alive who have keys to it, or know the combination. Besides, my own man is the one servant allowed in this room. So you see, Jack, I don't need to keep the box 'in sight' after Monsieur Defasquelle goes."
As he spoke, he walked toward an alcove at the left of the fireplace. It was fitted with bookshelves; and as Manners' eyes followed Claremanagh he remembered the secret of Silas Phayre's safe. Part of the top shelf had to be pulled out from the wall (after touching a spring) and then pushed up. Thus a small steel door was revealed, and could be unlocked only after a certain combination of letters had been made. Jack had not thought of the safe in years, or glanced in its direction on entering the room; but now, to his surprise, he saw that the bookshelf had already been pushed up, and the safe-door not only revealed, but opened.
Claremanagh's back was turned to him, and he could not see by a change of face whether Pat was vexed at his own forgetfulness, or indifferent. But Jack remembered the hidden fourth person in the room, and instinct told him that the safe had not been opened in readiness for the pearls. There had been some other motive. Claremanagh and the Polish woman had been interrupted in their tête-à-tête, and it would be characteristic of Pat if an unexpected rap on the door had caught him unawares. Could he have been in the act of giving Pavoya a jewel from the safe when he had been forced to answer a knock?
Luckily, no such suspicion could be in the Frenchman's head, for he had not seen Pavoya slip into the house. Jack glanced at him, and saw that he had laid the Duke's seal ring on the table beside the sealed packet. He was looking at the safe, but showed no surprise at finding it open. For him, it had been prepared to receive the pearls.
"_There's_ a good little hidie-hole!" said Pat. "Now I'll sign the receipt, Monsieur, and you may go to your engagement with a light heart." He went back to the table, took the box, and tossed it into the aperture in the wall. Then he closed the steel door, did something to it which the eyes of neither man could follow, and pulled down the concealing bookshelf.
