[3] These stories represented a phenomenon of Czech literature and were commonly known as cliftonky ("cliftonians", "Clifton tales"; singular: cliftonka).
The digital archive of Czech Academy of Sciences states that the only confirmed author of cliftonky was Alfons Bohumil Šťastný [cs].
For example, in 1925 Slovak writer Bedřich Beneš Buchlovan [cs] published "Nejposlednější dobrodružství Leona Cliftona" [The Last Adventure of Leon Clifton].
[1] During 1991–1994, Jaroslav Velinský, after writing over 30 stories about a (fictional) detective Ota Fink, tried to resurrect Clifton and published 5 cliftonky, with little success.
