London, 1668. It is two years since the city was devastated by the Great Fire, the inferno caused by a comet passing over the capital. But from the ashes rose the undead, hungry for the flesh of the living. Protecting the populous are zombie hunters like Titus Defoe, ex-Leveller and now agent of the crown. As Titus battles the zombie horde he comes to realise that some sort of intelligence is guiding them. Along with his Brethren of The Night, he must look deep into the rotten heart of the undead capital, to discover the cause of this evil canker!
