Charles "Fred" Hale comes to Brighton on assignment to anonymously distribute cards for a newspaper competition (this is a variant of "Lobby Lud" in which the name of the person to be spotted is "Kolley Kibber"). The antihero of the novel, Pinkie Brown, is a teenage sociopath and up-and-coming gangster. Hale had betrayed the former leader of the gang Pinkie now controls, by writing an article in the Daily Messenger about a slot machine racket for which the gang were responsible. Ida Arnold, a plump, kind-hearted and decent woman, is drawn into the action by a chance meeting with the terrified Hale after he has been threatened by Pinkie's gang. After being chased through the streets and lanes of Brighton, Hale accidentally meets Ida again on the Palace Pier, but eventually Pinkie murders Hale.
