A thrilling concoction ... Ackroyd's telling of the tale is a worthy revival - I found his book so creepy I kept the bedroom light on all night
Daily Express
A brilliant jeu d'esprit. Above all, it stands as a tribute to the power of the human imagination
Daily Telegraph
Ackroyd takes Mary Shelley's hint of a doppelganger and plays with it fascinatingly in a fast-paced thriller which also nods towards the notion of split personality enshrined in Stevenson's Jekyll and Hyde... The novel leaps to its climax nimbly as a pursuing fiend, adn ends suitably in fiery revelation
- Michele Roberts, Independent
Distinguished Frankensteinian fantasia...Ackroyd loves taking what we, the general reading public, think we know about great writers, only to twist that knowledge into new fictional shapes....Ackroyd is the great pretzel-baker of contemporary fiction. And this is one of his tastiest, and twistiest, products so far
Financial Times
Terrifying and fascinating in equal measure
