The world is big enough for us. No ghosts need apply. I fear that we cannot take Mr. Robert Ferguson very seriously. Possibly this note may be from him and may throw some light upon what is worrying him.”

He took up a second letter which had lain unnoticed upon the table while he had been absorbed with the first. This he began to read with a smile of amusement upon his face which gradually faded away into an expression of intense interest and concentration. When he had finished he sat for some little time lost in thought with the letter dangling from his fingers. Finally, with a start, he aroused himself from his reverie.

“Cheeseman's, Lamberley. Where is Lamberley, Watson?”

“It is in Sussex, south of Horsham.”

“Not very far, eh? And Cheeseman's?”

“I know that country, Holmes. It is full of old houses which are named after the men who built them centuries ago. You get Odley's and Harvey's and Carriton's—the folk are forgotten but their names live in their houses.

“Precisely,” said Holmes coldly. It was one of the peculiarities of his proud, self-contained nature that though he docketed any fresh information very quietly and accurately in his brain, he seldom made any acknowledgment to the giver. “I rather fancy we shall know a good deal more about Cheeseman's, Lamberley, before we are through. The letter is, as I had hoped, from Robert Ferguson. By the way, he claims acquaintance with you.”

“With me!”

“You had better read it.”

He handed the letter across. It was headed with the address quoted.

Dear Mr. Holmes [it said]:

I have been recommended to you by my lawyers, but indeed the matter is so extraordinarily delicate that it is most difficult to discuss. It concerns a friend for whom I am acting. This gentleman married some five years ago a Peruvian lady, the daughter of a Peruvian merchant, whom he had met in connection with the importation of nitrates. The lady was very beautiful, but the fact of her foreign birth and of her alien religion always caused a separation of interests and of feelings between husband and wife, so that after a time his love may have cooled towards her and he may have come to regard their union as a mistake. He felt there were sides of her character which he could never explore or understand. This was the more painful as she was as loving a wife as a man could have—to all appearance absolutely devoted.

Now for the point which I will make more plain when we meet. Indeed, this note is merely to give you a general idea of the situation and to ascertain whether you would care to interest yourself in the matter. The lady began to show some curious traits quite alien to her ordinarily sweet and gentle disposition. The gentleman had been married twice and he had one son by the first wife. This boy was now fifteen, a very charming and affectionate youth, though unhappily injured through an accident in childhood. Twice the wife was caught in the act of assaulting this poor lad in the most unprovoked way. Once she struck him with a stick and left a great weal on his arm.

This was a small matter, however, compared with her conduct to her own child, a dear boy just under one year of age. On one occasion about a month ago this child had been left by its nurse for a few minutes. A loud cry from the baby, as of pain, called the nurse back.
