"You will begin in each case by giving the outside porter one shilling.
Here are twenty-three shillings."

"Yes, sir."

"You will tell him that you want to see the waste-paper of yesterday.
You will say that an important telegram has miscarried and that you are
looking for it. You understand?"

"Yes, sir."

"But what you are really looking for is the centre page of the Times
with some holes cut in it with scissors. Here is a copy of the Times. It

but art, of which he had the crudest ideas, from our leaving the gallery
until we found ourselves at the Northumberland Hotel.

"Sir Henry Baskerville is upstairs expecting you," said the clerk. "He
asked me to show you up at once when you came."

"Have you any objection to my looking at your register?" said Holmes.

"Not in the least."

The book showed that two names had been added after that of Baskerville.
One was Theophilus Johnson and family, of Newcastle; the other Mrs.
Oldmore and maid, of High Lodge, Alton.

"Surely that must be the same Johnson whom I used to know," said Holmes
to the porter. "A lawyer, is he not, gray-headed, and walks with a

"No, sir, this is Mr. Johnson, the coal-owner, a very active gentleman,
