I am beginning to become a very big fan of Mary Higgins Clark. She is very good with plots and never giving away anything, but places every character under suspicion. This movie was excellent and I think it plays along the same lines as all her books/movies...in that you never can guess who did it until the end. I Would highly recommend this book and movie to anyone who like mysteries. However, I do not think it is available for sale because it is out of print. You may be able to buy it from a used or rare video store or see it on television. I watched it on the Lifetime Movie Network last night. IF you are interested in finding a copy online, then I would suggest ebay or inetvideo. I have purchased out of print/used videos that are in excellent condition.
