Nothing Is Impossible — Edward D. Hoch

Dr. Sam Hawthorne, a New England country doctor in the first half of the twentieth century, was constantly faced by murders in locked rooms and impossible disappearances. Nothing Is Impossible contains fifteen of Dr. Sam s most extraordinary cases solved between 1932 and 1936, including a circus acrobat who vanishes from a trapeze; an invisible weapon; murder in a cabin surrounded by unmarked snow; murder in a locked house surrounded by an electrified fence; the attack on a ventriloquist's dummy; a haunted teepee; the vanishing of a teenage girl from her blue bicycle; and eight other ingenious problems for Dr. Sam. The introduction is by Janet Hutchings, editor of Ellery Queen's Mystery Magazine.
