I have only one further note of this case. It is the letter which Holmes wrote in final answer to that with which the narrative begins. It ran thus:

BAKER STREET,
Nov. 21st.

Re Vampires.

SIR,—

Referring to your letter of the 19th, I beg to state that I have looked into the inquiry of your client, Mr. Robert Ferguson, of Ferguson and Muirhead, tea brokers, of Mincing Lane, and that the matter has been brought to a satisfactory conclusion. With thanks for your recommendation,

I am, Sir,
Faithfully yours,
SHERLOCK HOLMES.

THE ADVENTURE OF THE THREE GARRIDEBS

It may have been a comedy, or it may have been a tragedy. It cost one man his reason, it cost me a blood-letting, and it cost yet another man the penalties of the law. Yet there was certainly an element of comedy. Well, you shall judge for yourselves.
