Enola Holmes is back for one final mystery, and she faces a deadly foe - from the series that inspired the films, starring Millie Bobby Brown.

Read them all before the next film lands!

When Enola Holmes hears a muffled clanging sound coming from a 'safety coffin' in a chilly cemetery, she follows the sound to a crudely dug fresh grave. She starts digging . . . and inside a coffin she finds a girl who is drugged but not quite dead.

But how to find where the girl belongs - or where she is running from - when she can't remember anything about who she is? Only Enola could persevere to solve the mystery, in the face of a gang of heavies on her trail and her brother Sherlock's strict warning to stay away from the case.

'A story of a young girl who is empowered, capable, and smart . . . the Enola Holmes book series conveys an impactful message to kids and teenagers all over the world that you can do anything if you set your mind to it, and it does so in an exciting and adventurous way.' - MILLIE BOBBY BROWN
