Darren's sister has been murdered but her body has yet to be found. He wants to know what happened to her, so gets himself a cleaning job at the secure unit where the killer is being held. He behaves like an idiot but a good hearted idiot in his quest to discover the truth. The book was written well and was engaging, but not all the time plus I wasn't too keen on the twist or how it ended. I will read other books by this author.
