Odder Still - The Oddball Odyssey, #4

Someone is manipulating the actions of one of Oddball's team and Crocker, Oddball's quirky boss, tasks him with finding out what the hell is going on. But things straight away become complicated when the disfigured body of a senior government minister is found face-down in the River Thames near Windsor Castle. No sooner do they start looking into it when the mutilated body of a high-flying lawyer turns up in the same spot.
With no clues to work with, the team are up against it. Things turn even stranger when Harry Lewis arrives. Harry - real name Harriet - is a computer genius and she takes issue when she is manipulated into lighting candles in her sleep. No-one manipulates Harry Lewis and gets away with it. The bodies pile even higher when the charred remains of a Lord of the Realm are found in the entrance of his stately home.
But the strings finally come together when an unscrupulous journalist, Quentin Richards, finds himself staring down the barrel of a gun while his nemesis decides to amputate his manhood with a sharpened knife. Can Quentin escape the inevitable? It seems unlikely.
