"The Return of Moriarty" by John Gardner, published by Berkley in 1976.

A first edition paperback, 290 pages including a glossary.

This is a "very good plus" book, with the only reason I am not saying fine is that the original owner had the unfortunate habit of folding down the page corners to mark her spot, so pages 3/4, 5/6, and 13/14 corners are creased, with 21/22 currently folded. The good news is they never got farther than that, so the rest of the pages are all pristine. Super nice, a very little chip on front cover on bottom and thin reading crease along front spine edge.

Will ship promptly, carefully packaged.
