s gone to that celebrated London detective Mr.
Cadbury Taylor, and has engaged him to solve the diamond mystery. So
you see you will have a clear field. If you can leave for the castle
to-morrow night, you may have the pleasure of Mr. Cadbury Taylor's
company. He isn't visiting the castle, but goes straight to Vienna; so
if you work your cards rightly, you can be in the same carriage with
him as far as Munich, and during that time you may find out perhaps what
he thinks about the case. I know only this much about his theory, and
that is he thinks the right place to begin is in Vienna, where some, at

The heavy package was a typewriter in its case. Shortly before the train
departed, there sauntered into the station the tall, thin, well-known
form of the celebrated detective. He wore a light ulster that reached
almost to his heels, and his keen, alert face was entirely without beard
or moustache. As he came up the platform, a short, stout man accosted
him.

"I was afraid you were going to be late," said the detective's friend,
"but I see you are just in time as usual."

"A railway station," said Mr. Cadbury Taylor, "is not the most inspiring
place in London for the spending of a spare half hour; besides, I had
some facts to get together, which are now tabulated in my note-book, and
I'm quite ready to go, if the train is."

"I ha
