“I think, Inspector,” Holmes remarked, “that you would do well to telegraph for an escort, as, if my calculations prove to be correct, you may have a particularly dangerous prisoner to convey to the county jail. The boy who takes this note could no doubt forward your telegram. If there is an afternoon train to town, Watson, I think we should do well to take it, as I have a chemical analysis of some interest to finish, and this investigation draws rapidly to a close.”

When the youth had been dispatched with the note, Sherlock Holmes gave his instructions to the servants. If any visitor were to call asking for Mrs. Hilton Cubitt, no information should be given as to her condition, but he was to be shown at once into the drawing-room. He impressed these points upon them with the utmost earnestness. Finally he led the way into the drawing-room, with the remark that the business was now out of our hands, and that we must while away the time as best we might until we could see what was in store for us. The doctor had departed to his patients, and only the inspector and myself remained.
