“The Marquis had an intense passion for famous and historical jewels. He laid his plans far beforehand by installing himself as your secretary and getting his accomplice to obtain the situation of maid with your daughter, for whom he guessed the jewels were destined. And, though this was his matured and carefully thought-out plan, he did not scruple to attempt a shortcut by hiring a couple of apaches to waylay you in Paris on the night you bought the jewels. The plan failed, which hardly surprised him, I think. This plan was, so he thought, completely safe. No possible suspicion could attach to Richard Knighton. But like all great men⁠—and the Marquis was a great man⁠—he had his weaknesses. He fell genuinely in love with Miss Grey, and suspecting her liking for Derek Kettering, he could not resist the temptation to saddle him with the crime when the opportunity presented itself. And now, Monsieur Van Aldin, I am going to tell you something very curious. Miss Grey is not a fanciful woman by any means, yet she firmly believes that she felt your daughter’s presence beside her one day in the Casino Gardens at Monte Carlo, just after she had been having a long talk with Knighton.
