Harry Fowler is the kid who reads the adventures of Selwyn Pike in the pages of the Trump comic to his gang of Blood and Thunder Kids and becomes convinced that the strip is used as code by black marketeers. The police won’t believe him and he takes on the criminals himself, first visiting the sinister writer Alastair Sim and then working for grocer Nightingale (Jack Warner) who turns out to be central to the smuggling ring. After some false attempts to capture the criminals and stave off a department store robbery, and tying up Rhona (Valerie White) from the magazine, the scene is set for a standoff using Sim to engineer it in his story … Tremendous entertainment from writer TEB Clarke, with vivid performances from the kids running amok in the rubble-strewn bombed-out East End right after WW2. Ealing Comedy was really up and running in a film whose Expressionist leanings (courtesy of DoP Douglas Slocombe) remind one of Emil and the Detectives. Directed by Charles Crichton.
