My parents have always been big into the whole murder mystery/thriller/suspense scene and so I had a bit of an early introduction into the genre through this book. It still remains one of my favourites of Mary Higgins Clark. She is indeed the queen of suspense. Her little chapters make for quite a fast paced read... and also makes it easy to read just a little bit before bed.
This particular book has some great psychological twists that make the story all the more gripping.
