By William C. Dear and Carlton Stowers. Dear, author of The Dungeon Master, was called on by the family of Dean Milo to help crack that case; this is Dear's account, with Edgar-winner Stowers, of the Milo investigation.
This paperback edition doesn't have the superior art, and it isn't in great shape: visible shelfwear; a couple of cover creases; toned pages with some foxing to the flyleaves. But the spine is uncracked, the book sits straight, and it's somewhat scarce, so grab this one.
