A different style of novel to his Rebus series, but a captivating read full of plot twists and fully believable characters throughout. The book has three main characters who need to find the female assassin. They are assisted by a retired MI5 agent and a young woman from the French sister organisation. They combine their collective expertise to track down the assassin (code named Witch) who has landed in England to assassinate someone…but who is the target- A great read that is hard to put down.
