The Perfect Nanny. Since you know from page one that the nanny murdered the children in her care, there aren't any surprises. The book ends so suddenly, you're shocked. I guess that's the surprise. Anyway, I give this a D.
Lock Every Door. Billed as a taut psychological thriller, this book didn't deliver, at least not for me. It's the story of a young woman desperately in need of a job who gets one as apartment sitter in a Dakota-like building in New York, There she discovers scary secrets. Why doesn't she leave? I guess the author tried to give her reasons but I didn't buy them. The author, Riley Sager, has apparently written some really good thrillers. This was the first book of his that I read and, alas, I probably won't read a second.
Truth Worth Telling. Journalist Scott Pelley, formerly of CBS and prominently featured on Sixty Minutes has written a book about his career, mainly from 9/11 on, but also some about his early years as a teenager working in journalism. Each chapter features a different character trait--perseverance, valor, arrogance, courage--and ends with advice to young journalists. I found the book fascinating and well-written.
