“Sergeant Felton, from Scotland Yard, sir. Are you Lord Claythorpe?” “Yes,” said his lordship. “We’ve been watching the house,” said the man, “and we saw her dodging down the side passage which leads to your stables. Now then, young woman, let’s have a look at your face.” “No, no, no,” said the girl struggling, “there are reasons. The Chief Commissioner knows the reason.” Her captor hesitated and looked at his companion. “I think we’d better get the superintendent in charge of the case before we go any further, my lord,” he said. He took a pair of handcuffs from his pocket. “Hold out your hands,” he said, and snapped the glittering bracelets on her wrists. “Have you got a strong room, my lord, where I can keep her till the superintendent comes?” “In my library,” said his lordship. “Has it got a good door?” Lord Claythorpe smiled. He himself unlocked the library door and switched on the lights, and the girl was pushed into the room and on to a chair. The detective took a strap from his pocket and secured her ankles together. “I’m not taking any risks with you, my lady,” he said. “I don’t know who you are, but I shall know in a very short time. Now I want to telephone. Have you a telephone here?” “There is one in the hall.” The detective looked at the girl, and scratched his chin. “I don’t like leaving her alone, Robinson. You had better stay with her. Remember, you’re not to take your eyes off her, see?” They went out together, his lordship closing and locking the door behind them, whilst the man went in search of a telephone number. “By the way, you can hear my man if he shouts, can’t you?” he asked. “No,” said his lordship promptly. “You can hear nothing through that door. But surely your man is capable of looking after a girl?” Lewinstein, a silent spectator of these happenings, smiled. He had no illusions as to the resources of that girl, and was anxious to see the end of this adventure. In the meantime, behind the locked doors of the library the girl held out her hands and the “detective” with her unlocked the handcuffs. She bent and loosened the strap, then moved quickly to the wall where the ten safes were embedded. Each she examined quickly. “These are the three, Jimmy,” she said, and her companion nodded. “I won’t ask you how you know,” he said admiringly. “It was easy,” she said. “As soon as I got in here I gummed some thin black silk over the edges of each door. These three have been broken, so these three safes have been opened. We’ll take a chance on this one. Give me the key.” The “detective” opened a little leather case which he had taken from his pocket, and revealed some queerly shaped instruments. Three times the girl tried, each time withdrawing the tool from the keyhole to readjust the mechanism of her skeleton key, and at the third time the lock snapped back, and the door swung open. “Got it first time,” she said in triumph.
