It was past eleven o'clock when we formed our little ambuscade. Hopkins was for leaving the door of the hut open, but Holmes was of the opinion that this would rouse the suspicions of the stranger. The lock was a perfectly simple one, and only a strong blade was needed to push it back. Holmes also suggested that we should wait, not inside the hut, but outside it, among the bushes which grew round the farther window. In this way we should be able to watch our man if he struck a light, and see what his object was in this stealthy nocturnal visit.
It was a long and melancholy vigil, and yet brought with it something of the thrill which the hunter feels when he lies beside the water-pool, and waits for the coming of the thirsty beast of prey. What savage creature was it which might steal upon us out of the darkness?
