It was you we saw last night! she exclaimed.

You put on a diver's helmet. You had a thing like an empty cage in your hand. You went down under the water----

Ah, you saw that from the yacht, did you? broke in Essain.

I was afraid, when I caught sight of the passing yacht, that it might have been so! But it doesn't matter. Lord John fancies himself a detective--but it's luck, more than skill, which has favoured him so far: and his luck won't bring him to the bell buoy until I want him to come--which I shall do, later. The cage you saw isn't empty to-day, if any of Lord John's luck is on my friends' side, and I'm sure it is. I placed the receptacle ready last night. Now, I think it will be filled with jewelled fish, which I have come to catch. In their place I shall give it a feed of stones, heavy enough to hold it down. And deep under the still water you shall be its guardian, till I'm out of England and can let Lord John have a hint where to look for his lost wife.
