Simon Winchester remembers, hilariously, his first major professional mistake.
The victim of the first big mistake I ever made was a gentleman to whom I had never been properly introduced (and whose name I still do not know) but who was possessed of three singular qualities: he was alone in a room with me, he was without his trousers, and he was very, very dead.
Some context might be useful. It was the winter of 1962. I was eighteen years old and had taken a year off before going up to Oxford University. I also had a girlfriend far away in Montreal, and in the superheated enthusiasm of my puppy love, I had promised to visit her. The fact that I then lived in London and she three thousand miles away meant that fare money had to be amassed: I had to get a job, and one that paid well enough to allow me to get away to Canada as quickly as possible.
