Assault on England

The information comprises a photograph of Fergus's British Army commando unit in Cairo, 1942.

The only person of significance is Lieutenant John Elmore who became a renowned underworld assassin after the war before being killed in a shootout with police several years previously – although his body was never found.

Carter is briefed by the head of Special Operations Executive (SOE) and is assigned a young female agent (Heather York) to assist him.

Novosty escapes after a gunfight but leaves evidence behind that leads to a cottage in Lower Slaughter in the Cotswolds.

A clue left in the Foreign Secretary's office leads to Jupiter Motors a failing car factory in London.

Carter and York are captured by Jupiter's henchmen and driven to a large estate near Beaconsfield where they are imprisoned.

Carter and York search the rooms where a high-level ministerial meeting will be held expecting Jupiter to infiltrate and assassinate the Prime Minister.
