A really enjoyable listen. The version I had was a CD from Chivers Audio books, read by Shelley Thompson. She has a very good voice.
The story follows Susan Chandler, a psychologist with a radio show. Afer interviewing the writer of a book about the mysterious disappearances of a number of women, she starts investigating. The plot twists and turns, with a number of new friendships and a series of murders taking place. It is not certain who is responsible until the end of the book.
This is one of those books which refuse to be put down, so make sure you have the time to spare before opening that first page and starting to read.
