Death by Drowning

Ever driven under a river? A plot is under way to flood a heavily-travelled road tunnel under the River Thames while it is full of traffic in order to kill everybody in it. Willem van Piet, an agent in Britain's Serious Risks Office, is rushed back from abroad to investigate. He soon discovers a second murderous plot that is hidden behind the first one, and then there are the poison-pen letters he and his wife are receiving. These letters threaten their disabled young daughter with devastating injury. So are they connected to the murder plots? Death by Drowning is a story full of death, deception and treachery, with unexpected twists and turns, and an ending that is genuinely surprising.
