Walters, in her latest novel, has ventured into a new subject matter: psychological crime thriller. As usual, she creates a difficult and gruesome set of circumstances from which to spring her story. This time, however, it is a British soldier, Charles Acland, sustaining a terrible head wound while fighting in Iraq that launches this singularly complex journey into a world where he vainly struggles to recover his past. Along the way, he is going to meet people who will both help and hinder his search for why he's the way is: angry, suspicious, paranoid, and aggressive. His guardian angel will turn out to be the most unlikely individual - a husky, butchy female doctor posing as a weightlifter - who seems to possess the canny ability to both appeal to his gruff exterior and his less obvious, underlying gentleness. She and a female psychiatrist, Daisy, befriend Acland with the intent of taking him through the pressing and threatening issues in his life, while, at the same time, shielding him from a society and its criminal justice system that wants to write him of as a social monster and misfit. Don't be surprised to learn at the end that Walters has taken you on a journey full of non-sequitors meant to challenge one's grip on reality. Charles is definitely a chameleon character who has to sort out who he truly is, even if it means learning that he isn't that tough macho figure he always thought he was. What Charles discovers about himself is that he is not quite prepared to take on the truth about his vulnerable and addled life when it confronts him in full force. I like a Minette Walter's thriller because it is usually well orchestrated enough that I, the reader, has no problem following the labyrinth of her thinking.
