“Of course!”
“Then you must get Lucille out of that house. If she is left there she is absolutely lost to us. Apart from that, she is herself not safe. Our plan worked out too well. She is really in danger from this Duson affair.”
The laughter died away from Lady Carey’s face. She hesitated with her foot upon the step of her carriage.
“You can go back easily enough,” the Prince said. “You are the Duke’s cousin, and you were not included in his tirade. Lucille is in the morning-room, and here is the key. I brought it away with me. You must tell her that all our plans are broken, that we have certain knowledge that the police are on the track of this Duson affair. Get her to your house in Pont Street, and I will be round this afternoon. Or better still, take her to mine.”
Lady Carey stepped back on to the pavement. She was still, however, hesitating.
“Leave her with the Duke and Duchess,” the Prince said, “and she will dine with her husband to-night.”
Lady Carey took the key from his hand.
“I will try,” she said. “How shall you know whether I succeed?”
“I will wait in the gardens,” he answered. “I shall be out of sight, but I shall be able to see you come out. If you are alone I shall come to you. If she is with you I shall be at your house in an hour, and I promise you that she shall leave England to-night with me.”
“Poor Brott!” she murmured ironically.
