Sam's behaviour puzzled me. I do not know exactly what I expected him to do, but I certainly did not expect him to do nothing. Yet day followed day, and still he made no move. He was the very model of a butler. But our dealings with one another in London had left me vigilant, and his inaction did not disarm me. It sprang from patience, not from any weakening of purpose or despair of success. Sooner or later I knew he would act, swiftly and suddenly, with a plan perfected in every detail. But when he made his attack it was the very simplicity of his methods that tricked me, and only pure chance defeated him. I have said that it was the custom of the staff of masters at Sanstead House School--in other words, of every male adult in the house except Mr Fisher himself--to assemble in Mr Abney's study after dinner of an evening to drink coffee. It was a ceremony, like most of the ceremonies at an establishment such as a school, where things are run on a schedule, which knew of no variation. Sometimes Mr Abney would leave us immediately after the ceremony, but he never omitted to take his part in it first. On this particular evening, for the first time since the beginning of the term, I was seized with a prejudice against coffee. I had been sleeping badly for several nights, and I decided that abstention from coffee might remedy this. I waited, for form's sake, till Glossop and Mr Abney had filled their cups, then went to my room, where I lay down in the dark to wrestle with a more than usually pronounced fit of depression which had descended upon me. Solitude and darkness struck me as the suitable setting for my thoughts. At this moment Smooth Sam Fisher had no place in my meditations. My mind was not occupied with him at all. When, therefore, the door, which had been ajar, began to open slowly, I did not become instantly on the alert. Perhaps it was some sound, barely audible, that aroused me from my torpor and set my blood tingling with anticipation. Perhaps it was the way the door was opening. An honest draught does not move a door furtively, in jerks. I sat up noiseless, tense, and alert. And then, very quietly, somebody entered the room. There was only one person in Sanstead House who would enter a room like that. I was amused. The impudence of the thing tickled me. It seemed so foreign to Mr Fisher's usual cautious methods. This strolling in and helping oneself was certainly kidnapping _de luxe_. In the small hours I could have understood it; but at nine o'clock at night, with Glossop, Mr Abney and myself awake and liable to be met at any moment on the stairs, it was absurd. I marvelled at Smooth Sam's effrontery. I lay still. I imagined that, being in, he would switch on the electric light. He did, and I greeted him pleasantly. 'And what can I do for _you_, Mr Fisher?' For a man who had learned to control himself in difficult situations he took the shock badly. He uttered a startled exclamation and spun round, open-mouthed.
