I have posted some Mary Higgins Clark books in Hardback.  I also have one that I don't see an ISBN number A STRANGER IS WATCHING it's from the library and I got this from someone else on Paperback Swap, it has the something on the outside of the pages when you close the book like something was splashed on it but that is the way I received it as I said from another Paperback swap person.  WE are a smoking and Pet home.....
