I kept thinking over this, and also recalling his words when he spoke of Lady Ridsdale's diamonds as representing a fortune. What did he mean by saying that he would not let the means interfere with the end? That brief sentence sounded very much like the outburst of a desperate man. I could not help heartily wishing that Lady Ridsdale's diamond circlet was back in London, and, just before I dropped to sleep, I made up my mind to speak to Ridsdale on the subject.

Towards morning I did doze off, but I was awakened by hearing my name called, and, starting up, I saw Ridsdale standing by my side. His face looked queer and excited.

"Wake up, Bell," he cried; "a terrible thing has happened."

"What is it?" I asked.

"My wife's bracelet is stolen."

Like a flash I thought of Vyner, and then as quickly I knew that I must be careful to give no voice to hastily-formed suspicions.

"I won't be a moment dressing, and then I'll join you," I said.

Ridsdale nodded and left my cabin.

In five minutes I was with him on deck. He then told me briefly what had happened.

"Helena most imprudently left the case on her dressing-table last night," he said, "and owing to the heat she kept the window open. Some one must have waded into the water in the dark and stolen it. Perhaps one of the bandsmen may have noticed the flashing of the diamonds on her wrist and returned to secure the bracelet—there's no saying. The only too palpable fact is that it is gone—it was valued at twenty thousand pounds!"
