All But Impossible — Edward D. Hoch

Northmont, Connecticut, seemed to be haunted by ghosts, ghouls, and impossibilities, until Dr. Sam Hawthorne explained the seemingly impossible. All But Impossible contains fifteen of Dr. Sam's most extraordinary cases solved between 1936 and 1940, including A newly murdered corpse in a sealed tomb in a cemetery A body in a scarecrow A jug that turns water into wine -- poisoned wine A disappearance from a swimming pool A baby who becomes a child's doll on the way to being baptized An unfound door A room that appears and vanishes And eight other ingenious problems for Dr. Sam
