Ackroyd re-wrote the rules of the crime thriller with this cleverly conceived story, set in a very believable recreation of Victorian London. The author effortlessly blends fact and fiction as Dan Leno, king of the music-hall comedians is dragged into the investigation of one of London’s most notorious murders. When Karl Marx and Oscar Wilde are connected to the same crime the possibilities are endless. According to the Independent on Sunday ‘Ackroyd has pulled off the greatest coup of all, a four square crime novel…as aesthetically pleasing as it is morally shocking’. And the Observer called it ‘a flawlessly good read’.
