The tale I am setting out to tell has to do with the killing, on a May morning of the year 1919, of one young man by another who claimed, and still claims, to have been his friend. The circumstances were singular-perhaps even unique; the consequences affected a number of people in various interesting ways and byways; and since the manner of telling the story has been left entirely to me, I will begin with the breakfast-party that Philip Esdaile gave that morning at his studio in Lennox Street, Chelsea.
