For a charming week we wandered up the Valley of the Rhone, and then, branching off at Leuk, we made our way over the Gemmi Pass, still deep in snow, and so, by way of Interlaken, to Meiringen. It was a lovely trip, the dainty green of the spring below, the virgin white of the winter above; but it was clear to me that never for one instant did Holmes forget the shadow which lay across him. In the homely Alpine villages or in the lonely mountain passes, I could tell by his quick glancing eyes and his sharp scrutiny of every face that passed us, that he was well convinced that, walk where we would, we could not walk ourselves clear of the danger which was dogging our footsteps.
Once, I remember, as we passed over the Gemmi, and walked along the border of the melancholy Daubensee, a large rock which had been dislodged from the ridge upon our right clattered down and roared into the lake behind us. In an instant Holmes had raced up on to the ridge, and, standing upon a lofty pinnacle, craned his neck in every direction. It was in vain that our guide assured him that a fall of stones was a common chance in the spring-time at that spot. He said nothing, but he smiled at me with the air of a man who sees the fulfillment of that which he had expected.
And yet for all his watchfulness he was never depressed. On the contrary, I can never recollect having seen him in such exuberant spirits. Again and again he recurred to the fact that if he could be assured that society was freed from Professor Moriarty he would cheerfully bring his own career to a conclusion.
