Thomas H. Cook is one of my favorite writers for his haunting, lyrical prose. This book is one of his darker ones, delving into the depths of insanity, perhaps not as compelling as his award-winning Chatham School Affair, but no less brilliantly written. Its gradual buildup of suspense to the climax is flawless, and he has a way of drawing you into the fog that made me feel uneasy enough that I could not read this book at bedtime, having to put it down and move to lighter fare so I could finish it in daylight. His books are always an experience - read them.
