George calls on his now retired former colleague Toby Esterhase who tells him the General approached 2 weeks before his death and asked him to collect a document for him. Toby doesn't think much of the old General or some of his cronies such as Otto Leipzig, a peddler of information, most of it made up. George does remind him however that Otto's information about Moscow Centre, the headquarters of the KGB, was usually first-rate. George also visits Connie Sachs, Mother Russia as she was known before she retired from - or being pushed out of, she would say - the Circus. George wants her memory and she tells him of Otto Leipzig and a ginger-haired Soviet spy called Oleg Kirov, or the Ginger Pig, as Otto called him. They were university students together and unbeknown to Otto then, Kirov was already a spy shopping the more radical students to the authorities. Otto had run into Kirov in Paris struck up a friendship with him but by the time he had set Kirov up for the kill, so to speak, the Circus had gone off émigrés and didn't pursue it.
