What this book is about
A young couple is witnessed throwing themselves — or being thrown — from a bridge into the icy Thames. William Monk investigates what appears to be a double suicide and uncovers a dangerous truth beneath London's canals and sewers. Set partly in the great underground engineering works of Victorian London, the fifteenth William Monk novel is a dark, atmospheric mystery about desperation, secrets, and the violence that flows beneath respectable surfaces.
