This is the first book in the Senior Sleuth mystery series, and frankly, it wasn't that great. The other one that I read in the series (Death Takes The Surf, I think it was called) was a lot better. In this book we are getting to know the characters, and of course and old lady dies, so Kate and her friend try to solve the mystery. And as in most mysteries, the main character always gets in that sticky situation where the killer almost kills them. You always know that's going to happen.
So skip this one and read the other one. Its not really one of those series where you get confused if you haven't read the other ones first. That's a plus.
