Query: A Good Old Mystery Book

The Unseen Friend was a good, easy, mystery 'read'. It was suspenseful at the right time, and kept the reader wanting more..or at least to turn the next page! The characters, as well as the 'goings on' in the house were well thought out...and one could see the house, the characters and the various antics that occurred throughout the book in ones minds eye. It was refreshing to read, and I'm now waiting for the Unseen Friend #2.
