Query: Another hit by Mary Higgins Clark!

I have been reading books by Mary Higgins Clark for over 10 years now and I have never been disappointed. She is an amazing writer with a talent that is surpassed by few others. I could not put this book down. The characters were real, the plot was interesting and the end was gripping. Make yourself a cup of tea, get comfortable on your couch and relax. You will be entertained by this book.
