The protagonist, Dr.Peter Senden, is a freelancer working for a re-organised department of MI5 following government funding cuts. He’s haunted by an encounter at a money laundering seminar in Sweden when a Moldovan woman is murdered by the Russian SVR after she attempts to warn him that secrets of Britain’s main defence deterrent, the Astute Class submarine, have been exposed. He in turn survives an attempt on his own life before being recalled to Thames House where his department is given the task of establishing if there could be some truth in the woman’s story, or are the Russians playing the disinformation game. Does the warning refer to Mafia money laundering on enormous submarine materiel contracts or is there a technical leak involving communications and detection. Peter is in a relationship with Fran Johnstone, a pathologist, and together they try to establish if the security service has been jepardised. But, are the senior management holding something back from him? Will he discover the covert cooperation they have with a Kremlin organisation called Laundryman?
