The recollection of Peter's talk gave me the first real comfort that I had had that day. Peter had been a wise old bird, and these fellows I was after were about the pick of the aviary. What if they were playing Peter's game? A fool tries to look different: a clever man looks the same and is different.
Again, there was that other maxim of Peter's which had helped me when I had been a roadman. 'If you are playing a part, you will never keep it up unless you convince yourself that you are it.' That would explain the game of tennis. Those chaps didn't need to act,they just turned a handle and passed into another life,which came as naturally to them as the first. It sounds a platitude, but Peter used to say that it was the big secret of all the famous criminals.
