"She could be the most dangerous person in the room..." -- Cover.

From her first day as Personal Assistant to the celebrated Mina Appleton, Christine Butcher understands what is expected of her. Absolute loyalty. Absolute discretion. For twenty years, Christine has been a most devoted servant, a silent witness to everything in Mina's life. So quiet, you would hardly know she is there. Day after day, year after year, Christine has been there, invisible--watching, listening, absorbing all the secrets floating around her. Keeping them safe. Christine is trusted. But those years of loyalty and discretion come with a high price. And eventually Christina will pay. Yet, it would be a mistake to underestimate such a steadfast woman. Because as everyone is about to discover, there's a dangerous line between obedience and obsession.--Provided by publisher.
