The series was created by crime author Harlan Coben and is billed onscreen as 'Harlan Coben's Safe', with writing credited to Danny Brocklehurst, Mick Ford, Alex Ganley, and Karla Crome.

Although the story is set in England, the series is a French production by Canal+, which aired it via C8 in France while Netflix streamed it internationally outside France.

Filming took place in Manchester, Liverpool, and Cheshire, beginning in July 2017.

American actor Michael C. Hall, known for playing Dexter, was cast as the English lead character Tom Delaney, requiring him to perform in an English accent.

French actress Audrey Fleurot, known for French-language roles, was cast as Zoé Chahal in this English-language British production.

The show's theme song is 'Glitter and Gold' by Barns Courtney.

Several critics, including those at The Daily Telegraph and The Guardian, singled out Michael C. Hall's 'odd' English accent as a notable and somewhat divisive element of the series.

The series premiered simultaneously in 190 countries on 10 May 2018 and holds a 71% approval rating on Rotten Tomatoes based on 24 reviews.
