However, such was the animosity and fear between them that a mutually acceptable go-between, 28-year-old C18 member "Catford Chris" Castle, was driven to Sargent's mobile home in Harlow, Essex, by Browning, who waited in the car, while Castle went to visit Sargent. He was met at the door by Charlie Sargent and his political associate, the former Skrewdriver guitarist Martin Cross. Cross plunged a nine-inch (22 cm) blade into Castle's back.[13] Browning took Castle to hospital in a taxi, but doctors were unable to save him and he died shortly after arrival.
