Sam Sedgman discusses with Ivan six things which should be better known.

Sam Sedgman is a bestselling children's author, confirmed nerd and enthusiastic ferroequinologist. Co-creator of the award-winning 'Adventures on Trains' and 'Isaac Turner Investigates' series, he writes fact-based mystery and adventure stories for the young and young at heart.

Before writing stories for children, Sam worked as a digital producer at the National Theatre, which meant nosing around backstage with a camera and a microphone, cajoling theatre makers into explaining how stories get made. Forever interested in piecing things together, Sam is a lifelong fan of puzzles, games and detective fiction, and once founded a company making murder mystery treasure hunts for adventurous Londoners. His books have been translated into more than 20 languages.

When he isn’t writing, Sam can usually be found admiring a handsome timepiece, watching Alfred Hitchcock movies, or explaining some weird fact to you. He lives in London, on top of a railway station. You can find out more at https://samsedgman.com/.
