Written by Edward Stratemeyer himself, founder of the Stratemeyer Syndicate and creator of series like The Hardy Boys, Nancy Drew, Tom Swift, etc, this has somewhat of the flavor of a country house mystery as most, though not all, of the action takes place in and around a country house, and Adam Adams the detective has a slightly noir feeling to me--single, unperturbable, though not anti-romantic. While Adam Adams enjoys a sterling reputation in his world, he makes some dumb mistakes, but comes out right in the end, just like all book detectives. Enjoyable with an intriguing plot and interesting characters. Appropriate that I listed to the Librevox version driving to and from the Nancy Drew Sleuths Convention honoring the 115th anniversary of the Stratemeyer Syndicate!
