Influence is a thought-provoking thriller that dares the reader to question just how much we know about ourselves and the people we share our lives with. Marcus Kline is the world's leading authority on communication and influence. He can tell what you are thinking. He can see inside you. He can step inside your mind. In global demand as a consultant, Marcus Kline shares his expertise with world leaders, corporate giants and global media stars. Confident, self- assured and controlling, Marcus revels in his unparalleled skill. Yet when a series of murder victims bear the horrific hallmarks of an intelligent and remorseless serial killer, Detective Inspector Peter Jones turns to Marcus for help - and everything changes. Somewhere between Derren Brown in full control mode, and Tim Roth's Dr Cal Lightman in Lie to Me, is Marcus Kline a potential victim - or a sadistic and clever killer? Will you like Marcus? Will you hate him? You'll very likely do both, and you'll be influenced every step of the way, just like those in Marcus's life. At a time when we are increasingly driven by the power of communication, and the implications of persuasiveness, this is a timely, topical and frightening journey through the evil that influence can truly do. The book is supported by a unique and exciting website at http://marcuskline.co.uk which is already garnering a very positive and intrigued response.
