Holmes had read carefully a note which the last post had brought him. Then, with the dry chuckle which was his nearest approach to a laugh, he tossed it over to me.

"For a mixture of the modern and the mediaeval, if the practical and of the wildly fanciful, I think this is surely the limit," said he. "What do you make of it, Watson?"

I read as follows:

Re Vampires

SIR:

Our client, Mr. Robert Ferguson, of Ferguson and Muirhead, tea brokers, of Mincing Lane, has made some inquiry from us in a communication of even date concerning vampires. As our firm specializes entirely upon the assessment of machinery the matter hardly comes within our purview, and we have therefore recommended Mr. Ferguson to call upon you and lay the matter before you. We have not forgotten your successful action in the case of Matilda Briggs.

We are, sir,

Faithfully yours,

MORRISON, MORRISON, AND DODD.

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. As she ran into the room she saw her employer, the lady, leaning over the baby and apparently biting his neck. There was a small wound in the neck from which a stream of blood had escaped. The nurse was so horrified that she wished to call the husband, but the lady implored her not to do so and actually gave her five pounds as a price for her silence. No explanation was ever given, and for the moment the matter was passed over.

It left, however, a terrible impression upon the nurse's mind, and from that time she began to watch her mistress closely and to keep a closer guard upon the baby, whom she tenderly loved. It seemed to her that even as she watched the mother, so the mother watched her, and that every time she was compelled to leave the baby alone the mother was waiting to get at it. Day and night the nurse covered the child, and day and night the silent, watchful mother seemed to be lying in wait as a wolf waits for a lamb. It must read most incredible to you, and yet I beg you to take it seriously, for a child's life and a man's sanity may depend upon it.

At last there came one dreadful day when the facts could no longer be concealed from the husband. The nurse's nerve had given way; she could stand the strain no longer, and she made a clean breast of it all to the man. To him it seemed as wild a tale as it may now seem to you. He knew his wife to be a loving wife, and, save for the assaults upon her stepson, a loving mother. Why, then, should she wound her own dear little baby? He told the nurse that she was dreaming, that her suspicions were those of a lunatic, and that such libels upon her mistress were not to be tolerated. While they were talking a sudden cry of pain was heard. Nurse and master rushed together to the nursery. Imagine his feelings, Mr. Holmes, as he saw his wife rise from a kneeling position beside the cot and saw blood upon the child's exposed neck and upon the sheet. With a cry of horror, he turned his wife's face to the light and saw blood all round her lips. It was she - she beyond all question - who had drunk the poor baby's blood.

So the matter stands. She is now confined to her room. There has been no explanation. The husband is half demented. He knows, and I know, little of vampirism beyond the name. We had thought it was some wild tale of foreign parts. And yet here in the very heart of the English Sussex - well, all this can be discussed with you in the morning. Will you see me? Will you use your great powers in aiding a distracted man? If so, kindly wire to Ferguson, Cheeseman's, Lamberley, and I will be at your rooms by ten o'clock.

Yours faithfully,

ROBERT FERGUSON.

P. S. I believe your friend Watson played Rugby for Blackheath when I was three-quarter for Richmond. It is the only personal introduction which I can give.
