From relatively early on the comic also dabbled in science fiction. Issue 14 introduced a new character, Rod Collins - Special Agent in Space; shortly after this came stories such as Kidnapped by Martians (issue 23) and Revolt on Venus (issue 35).
Issue 37, with its story "Crime Rides the Spaceways", introduced a longer-lasting spacefaring detective named Rick Random. Although the science fiction stories accounted for a surprisingly large chunk of the comic's output during this time, there was still time for more traditional detectives: Sherlock Holmes made his debut in issue 65. Around the same time the comic also introduced Inspector Chafik of the Baghdad Police and the female detective Lesley Shane; these two emerged, alongside Rick Random, as the comic's main characters.
Later, the comic begun to rely heavily on reprints of the American strip Rip Kirby, the original characters - aside from Rick Random - being sidelined in the process. Reprints of the British newspaper strip Buck Ryan also began appearing towards the end of the comic's life, along with John Steel, a character who also appeared in Thriller Picture Library.
