My review -
Tom Markland is rescued from Canary Wharf after almost drowning. He loses his memory as a result but when it begins to return he recalls the strangling of four young women - apparently by himself. Gradually his memory returns and he finds he is a journalist who was engaged in investigating a company's huge financial irregularity. He is in danger from the company boss and his enforcer and also from the real killer of the girls.
The story is an exciting one with a tangled web of characters and motives which the investigative journalist teases apart, only to find he's still not at the end of the journey. I too found I jumped to erroneous conclusions and the swift changes kept me on my toes. This is an action-packed thriller in which, although the story unfolds and results are achieved, there is a slightly unsettling ending. I loved it!
