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.
