The Japanese form of Golden Age detective fiction was re-launched in the early 1980s as shin honkaku by Soji Shimada and Yukito Ayatsuji, but the original honkaku dates from the 1930s and one of its pioneers was Keikichi Osaka. The Ginza Ghost is a collection of twelve of his best stories, almost all impossible crimes. Although the solutions are strictly fair-play, there is an unreal, almost hallucinatory quality to them. Osaka, who died tragically young, was an early pioneer and master of the genre, whose work is only now starting to be re-discovered. Readers of LRI’s The Decagon house Murders and The Moai Island Puzzle will not be disappointed. Locked Room International discovers and publishes impossible crime mysteries from all over the world, by authors past and present.
