Note received by Sherlock Holmes from Stanley Hopkins

“Abbey Grange, Marsham, Kent, 3:30 A.M.
“MY DEAR MR. HOLMES:
I should be very glad of your immediate assistance in what promises to be a most remarkable case. It is something quite in your line. Except for releasing the lady I will see that everything is kept exactly as I have found it, but I beg you not to lose an instant, as it is difficult to leave Sir Eustace there.
“Yours faithfully, “STANLEY HOPKINS.
