Let the record state that The Wailing Rock Murders (1932) is the seventh title I’ve read from the Roland Lacourbe-curated Locked Room Library list to not actually contain an impossible crime. Others of this distinction have run the gamut from wonderful to utterly forgettable, so an absence of impossibility is not to be held against it, and Clifford Orr’s second and final novel undeniably contains plenty of locked rooms…but they’re the ‘locked from the outside’ variety, whose very nature should not be confused with the sort of thing we (are meant to) mean when throwing a term like ‘locked room mystery’ about.
