Lucas Rocco

France, 1963. Taken out of his home town as part of a nationwide “initiative”, Inspector Lucas Rocco finds himself in the village of Poissons-Les-Marais, Picardie – and answerable to his former army CO Francois Massin. On his first day he finds a murdered woman wearing a Gestapo uniform lying in a British military cemetery. When the body is removed from the mortuary before Rocco can finish his investigation, he traces the paperwork to the dead woman’s father, industrialist Philippe Bayer-Berbier.

Picardie, 1963. A truck drops a group of illegal workers by a deserted stretch of canal in the dead of night, desperate travellers in a pipeline, searching for a better life. Days later, one of them surfaces, stabbed to death. For Inspector Lucas Rocco, finding the victim's fellow travellers presents problems. Most Algerian immigrants are welcome, but trawling for any who aren't is a sensitive issue loaded with threats of civil unrest - something which terrifies his bosses in the Ministry.

1963, France: A farmer reports a truck ramming into a car near Picardie, followed by gunfire. A group of Englishmen are brought in after a bar fight. A tramp's body is discovered in a burnt out truck. All this occurring after multiple attempts on the President's life. Inspector Lucas Rocco knows there's a connection somewhere, and is recruited by Colonel Saint-Cloud to assist with the President's Security.

Picardie, France, 1964, the exclusive Clos du Lac sanitarium: A man is discovered standing in the therapy pool. But he's not there for his health; someone has chained him to the bottom and left him to die very, very slowly. Inspector Lucas Rocco believes it's an unusual and elaborate method of execution. But nobody seems to have heard or seen anything, the staff are resolutely unhelpful - or dead - and ministry officials sent from Paris to 'assist' attempt to impede Rocco's efforts to find answers.
