When a rotting torso is discovered in the vault of New Scotland Yard, it doesn't take Dr Thomas Bond, Police Surgeon, long to realise that there is a second killer at work in the city where, only a few days before, Jack the Ripper brutally murdered two women in one night.

Is it a man who has brought mayhem to the streets of London, or a monster?
