In Rush of Blood by Mark Billingham three British couples meet on holiday in Florida and are witnesses to the disappearance of a child from the resort. Rush of Blood is told thorough the back stories of the three couples and their interactions once they have returned home as the investigation unfolds on both sides of the Atlantic. Gradually you realise that one of the 6 was responsible for abducting the child.
Rush of Blood is challenging because all of the characters are unpleasant and yet at the same time you are aware that much of this is misdirection. I read this with a sense of fascination watching a train crash in slow motion and at the same time eager for it to be over. Mark Billingham is usually much better than this, if you have enjoyed his Tom Thorne series you may be disappointed by this stand alone novel
