A cop is nearly killed and is still suffering recent-term amnesia when he leaves hospital. He is made to feel very unwelcome by his superiors who believe he remains stupidly obsessed with trying to find a girl long given up as missing or dead. He tries to recollect what happened to him and to find the link, if any, to the missing girl - he does this with unofficial help, having lost his position on the force, and the support of friends and even some aides. This is a very well-constructed story, with plenty of twists and turns, which keeps you guessing until the end. The writing is unexceptional but contains it share of wit and the story-line development and characterisations are impressive : it would be difficult not to warm to Vincent Ruiz and his Professor friend Joe. There must therefore be a sequel looming and I very much look forward to it. 9/10
