The shoot-out takes place at the Saint's house in Maidenhead. Marius' henchmen are lining the hedge shooting in (the police are on their way), there's a car with the engine running outside, two boats in the river at the bottom of the garden and a stand-off in the house with the Saint, Norman Kent, the Crown Prince, Rayt Marius and a British Secret Service agent. Patricia is loose in the house with a gun and the Professor is down in the cellar, shot dead by Norman Kent. Norman Kent has the professor's notes on how to build an electroncloud machine. What a scenario!
