"Because you will find me a dangerous companion now. This man's occupation is gone. He is lost if returns to London. If I read his character right he will devote his whole energies to revenging himself upon me. He said as much in our short interview, and I fancy that he meant it. I should certainly recommend you to return to your practice."
It was hardly an appeal to be successful with one who was an old campaigner as well as an old friend. We sat in the Strasburg salle-à-manger arguing the question for half an hour, but the same night we had resumed our journey and were well on our way to Geneva.
For a charming week we wandered up the Valley of the Rhône, 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 still 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. 
"A large rock clattered down."
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 fulfilment 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.
"I think that I may go so far as to say, Watson, that I have not lived wholly in vain," he remarked. "If my record were closed to-night I could still survey it with equanimity. The air of London is the sweeter for my presence. In over a thousand cases I am not aware that I have ever used my powers upon the wrong side. Of late I have been tempted to look into the problems furnished by Nature rather than those more superficial ones for which our artificial state of society is responsible. Your memoirs will draw to an end, Watson, upon the day that I crown my career by the capture or extinction of the most dangerous and capable criminal in Europe."
I shall be brief, and yet exact, in the little which remains for me to tell. It is not a subject on which I would willingly dwell, and yet I am conscious that a duty devolves upon me to omit no detail.
It was upon the 3rd of May that we reached the little village of Meiringen, where we put up at the Englischer Hof, then kept
