Edgar Wallace 
The Flying Squad 

The creek between the canal and the river flows under Lady’s Stairs, a crazy wooden house inhabited by Li Yoseph – known to the police as a smuggler. The neighborhood suspects he is rich, and knows he is mad. Inspector Bradley is out to break a drug-smuggling gang which operates from an old house overhanging the Thames; the gang is headed by a criminal called Mark Mc Gill. The disappearance of young Ron Perryman – whom Mc Gill has murdered and dumped in the river – gives the Inspector his ideal opportunity to begin asking questions… Edgar Wallace established his reputation as a writer of detective thrillers, a genre in which he wrote more than 170 books, with the publication of „The Four Just Men”.
