The year is 1865. Falsely imprisoned for high treason, Captain John Ashton awaits execution by hanging - but instead finds himself a free man, albeit stripped of his title, fortune and even identity, thanks to a mysterious secret society known as the Hellfire Club. On the run from the law and desperate to redeem his good name, Ashton assumes the guise of Spring Heeled Jack, an agile, phantomesque figure of folklore. He begins a campaign of harassment and intimidation against those who framed him. Quickly, however, he finds himself drawn into the intrigues of London's shadow-world, including a deadly game of cat and mouse against a rooftop-dwelling serial killer ...In the great tradition of penny dreadful adventure tales, this action-packed novel reimagines the urban legend of Spring Heeled Jack as a superhero origin story, told as the memoir and confession of Spring Heeled Jack himself.
