I asked for Lady Dorothy, who at once said to me:

"The ring was found yesterday by Mr Lestrade."

"I know," I answered, "but which ring?"

She could not repress a slight twitch of the eyelids as she said: "There was only one ring."

I told her of my discovery and of my investigations.

"This is a very odd coincidence, Mr Holmes," she said. "Some one else must have ordered an imitation. But you shall examine my ring for yourself." Where-upon she fetched the ring, and I saw it was no imitation. She had of course in the meantime found the real ring.

But to my intense annoyance she took it to Lestrade and said to him:

"Isn't this the ring you found yesterday, Mr Lestrade?"

Lestrade examined it and said, "Of course it is absolutely identical in every respect."

"And do you think it is an imitation?" asked this most provoking young lady.
