In a city on the brink of acquiring a vast empire, seven men are struggling for power. Cicero is consul, Caesar his ruthless young rival, Pompey the republic’s greatest general, Crassus its richest man, Cato a political fanatic, Catilina a psychopath, Clodius an ambitious playboy.

The stories of these real historical figures – their alliances and betrayals, their cruelties and seductions, their brilliance and their crimes – are all interleaved to form this epic novel. Its narrator is Tiro, a slave who serves as confidential secretary to the wily, humane, complex Cicero. He knows all his master’s secrets – a dangerous position to be in.

From the discovery of a child’s mutilated body, through judicial execution and a scandalous trial, to the brutal unleashing of the Roman mob, Lustrum is a study in the timeless enticements and horrors of power.

The stranger is a Sicilian, a victim of the island’s corrupt Roman governor, Verres. The senator is Cicero, a brilliant young lawyer and spellbinding orator, determined to attain imperium – supreme power in the state.

This is the starting-point of Robert Harris’s most accomplished novel to date. Compellingly written in Tiro’s voice, it takes us inside the violent, treacherous world of Roman politics, to describe how one man – clever, compassionate, devious, vulnerable – fought to reach the top.

‘Sometimes it is foolish to articulate an ambition too early – exposing it prematurely to the laughter and scepticism of the world can destroy it before it is even properly born. But sometimes the opposite occurs, and the very act of mentioning a thing makes it suddenly seem possible, even plausible. That was how it was that night. When Cicero pronounced the word “consul” he planted it in the ground like a standard for us all to admire. And for a moment we glimpsed the brilliant, starry future through his eyes, and saw that he was right: that if he took down Verres, he had a chance; that he might – just – with luck – go all the way to the summit…’

There was a time when Cicero held Caesar’s life in the palm of his hand. But now Caesar is the dominant figure and Cicero’s life is in ruins.

Exiled, separated from his wife and children, his possessions confiscated, his life constantly in danger, Cicero is tormented by the knowledge that he has sacrificed power for the sake of his principles.

His comeback requires wit, skill and courage – and for a brief and glorious period, the legendary orator is once more the supreme senator in Rome.

But politics is never static and no statesman, however cunning, can safeguard against the ambition and corruption of others.

Riveting and tumultuous, DICTATOR encompasses some of the most epic events in human history yet is also an intimate portrait of a brilliant, flawed, frequently fearful yet ultimately brave man – a hero for his time and for ours. This is an unforgettable tour de force from a master storyteller.
