There are some nights when I envy those who sleep. I have not slept since World War 2.1, when a sliver of North Korean shrapnel entered my mind and found its way to something called the sleep center, whereupon I entered a state of permanent insomnia. I was eighteen when this happened, and by now I can barely remember what sleep was like.

In the past few years scientists have taken an interest in sleep. They’ve been trying to determine just why people sleep, and what dreams do, and what happens when a person is prevented from sleeping and dreaming. I could probably answer a few of their questions. When a person is prevented from sleeping and dreaming he embraces a wide variety of lost causes, studies dozens of languages, eats five or six meals a day, and uses his life to furnish those elements of fantasy that other men find in dreams. This may not be how it works for every absolute insomniac, but it’s how it works for the only absolute insomniac I know, and for the most part I’m quite happy with it. After all, why waste eight hours a night sleeping when, with proper application, one can waste all twenty-four wide awake?

Yet there are times when sleep would be a pleasure, if only because it provides a subjectively speedy way to get from one day to the next when there is absolutely nothing else to do. This was one of those times. Nigel and Julia had repaired to their separate bedrooms. There was no one in London whom I wanted to see. The hunt for Smythe-Carson and Carradine would have to wait until morning. Meanwhile…

Meanwhile what?

Meanwhile I bathed and shaved and put on reasonably clean clothes and drank tea with milk and sugar and fried up some eggs and bacon and read part of a collection of the Best Plays of 1954 (which were none too good) and stretched out on my back on the floor for twenty minutes of Yoga-style relaxation. This last involves flexing and relaxing muscle groups in turn, then blanking the mind through a variety of mental disciplines. The mind-blanking part of it was easier than usual this time because my mind was very nearly empty to begin with.
