“For England, home and beauty—eh, Watson? Martyrs on the altar of our country. But what do you think of it, Mycroft?” “Excellent, Sherlock! Admirable! But what use will you make of it?” Holmes picked up the _Daily Telegraph_ which lay upon the table. “Have you seen Pierrot’s advertisement to-day?” “What? Another one?” “Yes, here it is: “To-night. Same hour. Same place. Two taps. Most vitally important. Your own safety at stake.—Pierrot. “By George!” cried Lestrade. “If he answers that we’ve got him!” “That was my idea when I put it in. I think if you could both make it convenient to come with us about eight o’clock to Caulfield Gardens we might possibly get a little nearer to a solution.” One of the most remarkable characteristics of Sherlock Holmes was his power of throwing his brain out of action and switching all his thoughts on to lighter things whenever he had convinced himself that he could no longer work to advantage. I remember that during the whole of that memorable day he lost himself in a monograph which he had undertaken upon the Polyphonic Motets of Lassus. For my own part I had none of this power of detachment, and the day, in consequence, appeared to be interminable. The great national importance of the issue, the suspense in high quarters, the direct nature of the experiment which we were trying—all combined to work upon my nerve. It was a relief to me when at last, after a light dinner, we set out upon our expedition. Lestrade and Mycroft met us by appointment at the outside of Gloucester Road Station. The area door of Oberstein’s house had been left open the night before, and it was necessary for me, as Mycroft Holmes absolutely and indignantly declined to climb the railings, to pass in and open the hall door. By nine o’clock we were all seated in the study, waiting patiently for our man. An hour passed and yet another. When eleven struck, the measured beat of the great church clock seemed to sound the dirge of our hopes. Lestrade and Mycroft were fidgeting in their seats and looking twice a minute at their watches. Holmes sat silent and composed, his eyelids half shut, but every sense on the alert. He raised his head with a sudden jerk. “He is coming,” said he.
