My first impression was that the stranger's eyes were of an unusually light blue. They met mine for several blank seconds, vacant, unmistakably scared. Startled and innocently naughty, they half reminded me of an incident I couldn't quite place; something which had happened a long time ago, to do with the upper fourth form classroom. They were the eyes of a schoolboy surprised in the act of breaking one of the rules. Not that I had caught him, apparently, at anything except his own thoughts: perhaps he imagined I could read them. At any rate, he seemed not to have heard or seen me cross the compartment from my corner to his own, for he started violently at the sound of my voice; so violently, indeed, that his nervous recoil hit me like repercussion. Instinctively I took a pace backwards.
