Het politieraadsel (The Police Puzzle) is episode 126 of the Lord Lister pulp series, published in Dutch. The Lord Lister franchise was a long-running early twentieth-century serial — originating in Germany and widely translated — following the adventures of a suave gentleman thief in the tradition of E. W. Hornung’s Raffles.
By instalment 126 the series had accumulated a devoted readership drawn to its reliable blend of clever plotting and period atmosphere. This free public-domain EPUB delivers a compact, entertaining episode of early popular crime fiction in the Dutch language.
