When a rotting torso is discovered in the vault of New Scotland Yard, it doesn't take Dr. Thomas Bond, Police Surgeon, long to realize 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.

And, as more headless and limbless torsos find their way into the Thames, Dr. Bond becomes obsessed with finding the killer.
