There was another eruption of laughter, everyone joining in. The-potmen moved about, carrying trays crammed with glasses and tankards, showing unbelievable balance and dexterity. The bar itself was so crowded that Lemaitre was pressed hard against a corner. He lit cigarette after cigarette from the previous butt and kept glancing at the door, ostensibly on the look-out for his wife. But Charlie Blake did not come.

An hour earlier, Charlie Blake had left his tiny house in Whitechapel and started out for the Old Steps.

He was a man in his middle fifties, not unlike Lemaitre to look at, but smaller and more dapper, with thick hair, dyed jet-black, and slightly fuller in the face. A card-player of remarkable skill, he crossed the Atlantic two or three times each year, playing cards and making nearly enough money to live by. He made still more by picking up racing information and passing it on. He knew better than most people how much loose talk there was in the big smoking-rooms of the transatlantic liners, especially at the end of an evening of heavy drinking, and he made full use of this.

He was in many ways a nice little man. His wife was fond of him, although she entertained lovers quite shamelessly whenever Charlie was away. She kept his small but pleasantly-appointed house in good order, and fed him well. He was generous with the children of his neighbours -he himself was childless — and he greatly enjoyed walking.

On this hot summer night, he was dressed as coolly as anyone in London, wearing a beige-coloured linen jacket and tropical-weight trousers, with openwork brown-and-white shoes. Now and again he eased his collar: the heat always gave him a rash on the neck and he used a special ointment to soothe the irritation; but in such heat as this, the collar seemed to stick to the ointment. He walked quite briskly and it did not enter his mind that he was in any kind of danger.

Still less did the possibility of danger occur to him when he saw a taxi driven by an acquaintance pull up.
