In East London in the summer of 1895, Robert Coombes (age thirteen) and his brother Nattie (age twelve) were arrested for matricide and sent for trial at the Old Bailey. Robert confessed to having stabbed his mother, but his lawyers argued that he was insane - his young mind twisted by the content of penny dreadfuls, the pulp fiction of the time, which the youngster obsessively read. The judge sentenced him to detention in Broadmoor, the most infamous criminal lunatic asylum in the land. Shockingly, Broadmoor turned out to be the beginning of a new life for Robert. At a time of great tumult and uncertainty, Robert Coombes's case crystallized contemporary anxieties about the education of the working classes, the dangers of pulp fiction, and evolving theories of criminality, childhood, and insanity. With riveting detail and rich atmosphere, Summerscale re-creates this terrible crime and its aftermath, uncovering an extraordinary story of man's capacity to overcome the past.
