Here is a very nice condition 1967 hardcover book from the Alfred Hitchcock and The Three Investigators series entitled THE MYSTERY OF THE  SILVER SPIDER.

It has 184 pages and has only minor wear to cover and edges of spine, which is intact.

Some minor staining to outer edges of pages.

Book has a very SLIGHT slant.

Overall, I'd say an 8 out of ten.

Thanks for your interest!
