On 11 May 1812 Spencer Perceval, the British Prime Minister, was fatally shot at close range in the lobby of the House of Commons. In the confused aftermath, his assailant, John Bellingham, made no effort to escape. A week later, before his motives could be examined, he was tried and hanged. Here, for the first time, the historian Andro Linklater looks past the conventional image of Bellingham as a 'deranged businessman' and portrays him as an individual, driven by the anxieties of his family life, by his yearning for respectability and by the raw emotions that convulsed his home town of Liverpool. But as the evidence accumulates, a wider, darker picture emerges.
