Gianni Orzan has no reason to feel unhappy. He has just been awarded a prize for his children's writing and a cheque for fifteen million lire. He is blissfully married to Anna and is a doting father to an eight-year-old son, Franceschino. He loves film and is an avid chess player. He is a man in complete control of his life.

But when Gianni leaves the award ceremony, a chain of events are set in motion that will shatter this perfect life. In an uncharacteristically rash moment he accepts a ride from an unlicensed cab driver. As soon as the car pulls off he feels unnerved. At the first set of lights the driver turns, smiles at Gianni, a pistol butt poking from his belt, and says - 'So, Franceschino has finally learned to ride his bicycle...'. Gianni bolts from the cab. But it's too late; in this briefest of moments the serenity of Gianni Orzan's life has been destroyed.

Later, after he has sent his wife and son to stay with family, the same cab driver appears at his door and introduces himself as Gianni's father's oldest friend. He certainly talks accurately about Gianni's father, who died less than a fortnight ago. In fact, he seems to know much more about Gianni's respectable, pious father than Gianni ever did, or perhaps ever wants to.

Reminiscent of Ian McEwan's 'Enduring Love', 'The Force of the Past' is a breathtakingly clever and entirely gripping story of how a calm, ordinary life can rapidly unravel.
