Something''s in the water... A chilling new thriller from the next Queen of Crime.      Young policewoman Lacey Flint knows that the Thames is a dangerous place -- after all, she lives on it and works on it -- but she''s always been lucky. Until one day, when she finds a body floating in the water. Who was this woman and why was she wrapped so carefully in white burial cloths before being hidden in the fast-flowing depths?      DCI Dana Tulloch hates to admit it, but she''s fond of the mysterious Lacey. Even if she keeps on interfering in her investigations, and is meddling with the latest floater case. But now she's got to break some terrible news to her -- news that could destroy Lacey's fragile state of mind.      And Lacey will need to keep her wits about her because there's a killer that's lurking around her boat, leaving her gifts she'd rather not receive.
