Night Walk — Elizabeth Daly

From Agatha Christie's favorite American author -- a 1940s amateur sleuth must save a friend accused of murder in a small New York town.

Frazer's Mills, in Westchester County, New York, is a small, isolated village, where everyone knows everyone else and things haven't changed much (and the mills have been closed for quite some time). When murder suddenly intrudes upon this sedate rural backwater, antiquarian book dealer Henry Gamadge arrives to solve the mystery and restore order.

“One of Daly's best . . . an engrossing tale, both for its problem and for its setting.” -- Curt Evans, The Passing Tramp blog
