Professional 'cleaner' Jonathan Quinn has a new client and a odd job: find and remove the remains of a body hidden twenty years ago inside the walls of a London building, before the building is demolished. But Quinn and his team are being watched. Suddenly caught in the crossfire between two dangerous rivals, Quinn must unravel the identity of the body and why it still poses so great a threat even in death. Because a plot stretching from the former Soviet Union to Hong Kong, from Paris to London, from Los Angeles to Maine is rapidly falling apart. And Quinn hasn't just been hired to tie up loose ends - he is one.
