❗️Last Chance❗️4/$20- Vintage A Stranger is Watching Book by Mary Higgins Clark

Vintage 1977 hardcover copy of A Stranger is Watching by Mary Higgins Clark. This is the second suspense book she published. I think this copy might be a first edition, but can’t find information to verify. There is no ISBN. Still a great vintage copy in good condition, with some damage to the dust jacket and a dent on the bottom corner of the hardcover. See photos for more details.
