“To go to Baskerville Hall.”
“And when?”
“At the end of the week.”
“On the whole,” said Holmes, “I think that your decision is a wise one. I have ample evidence that you are being dogged in London, and amid the millions of this great city it is difficult to discover who these people are or what their object can be. If their intentions are evil they might do you a mischief, and we should be powerless to prevent it. You did not know, Dr. Mortimer, that you were followed this morning from my house?”
Dr. Mortimer started violently. “Followed! By whom?”
“That, unfortunately, is what I cannot tell you. Have you among your neighbours or acquaintances on Dartmoor any man with a black, full beard?”
“No—or, let me see—why, yes. Barrymore, Sir Charles’s butler, is a man with a full, black beard.”
“Ha! Where is Barrymore?”
“He is in charge of the Hall.”
“We had best ascertain if he is really there, or if by any possibility he might be in London.”
“How can you do that?”
“Give me a telegraph form. ‘Is all ready for Sir Henry?’ That will do. Address to Mr. Barrymore, Baskerville Hall. What is the nearest telegraph-office? Grimpen. Very good, we will send a second wire to the postmaster, Grimpen: ‘Telegram to Mr. Barrymore to be delivered into his own hand. If absent, please return wire to Sir Henry Baskerville, Northumberland Hotel.’ That should let us know before evening whether Barrymore is at his post in Devonshire or not.”
