He replaced the receiver, listened and waited. In a few moments there was the sound of a light footstep outside. The door was opened and Pamela entered. She was still wearing the grey tailor-made costume in which she had left the steamer.

"Why, where is Mr. Van Teyl?" she asked, looking around the room. "I have been ringing up for the last ten minutes and couldn't get any answer. I did not realise that it was the next suite."

"Mr. Van Teyl is close at hand, madam," Nikasti replied. "If you will kindly be seated, I will fetch him."

"How long have you been valet here?" Pamela asked curiously.

"For a few hours only, madam," was the grave reply. "If you will be so good as to wait."

He bowed low and left the room. Pamela took up an evening paper and for a few minutes buried herself in its contents. Then suddenly she held it away from her and listened. A queer and unaccountable impulse inspired her with a certain mistrust. There was no sound of movement in the adjoining bedchamber, nor any sign of her brother's presence. She opened the door and peered in. It was empty and in darkness. Then, moved by that same unaccountable impulse, she crossed the room and listened at the door which led into her own suite, and which she perceived was bolted on this side as well as her own. She listened at first idly, afterwards breathlessly. In a few moments she was convinced that her senses were not playing her false. Some one was moving stealthily about in her room, the key to which was even at that moment in her hand. She hastened to the door, to be confronted by another surprise. The handle turned but the door refused to open. She was locked in.

Pamela was both generous and insistent in the matter of bells. She found four, and she rang them all together. The consequences were speedy, and in their way satisfactory. Nikasti himself, a breathless chambermaid, a hurt but dignified waiter, and the floor valet, who had not even stopped to put on his coat, entered together. They seemed a little stupefied at finding Pamela alone and no sign of any disturbance.

"Why was I locked in here?" Pamela demanded indignantly, taking them en bloc.

There was a little chorus of non-comprehension. Nikasti stepped forward, waved to the others to be silent, and bowed almost to the ground.

"It was a mistake easily to be understood, madam," he explained. "The handle is a little stiff, perhaps, but the door was not locked. We all reached here together, I myself barely a yard in advance. No key was used—and behold!"
