I remember reading a lot of these books and the series often wandered into the realms of science fiction, fantasy and horror. Interestingly, my two favourites were more down to earth choices: The Deadly Shadow, which involved the global hunt for a Russian spy that was literally a ticking time bomb, and Mountain Survival – a plane crash in the Rocky Mountains survivalist story that Bear Grylls would have been proud of. I have fond memories of these
books as a child.
Do you remember any?
