It’s a great time to be a fan of adaptations, from Hollywood adapting classic mystery novels through upcoming releases to many big-name actors being cast. This month fans of mystery and thriller adaptations can look forward to watching Patrick Dempsey as a hitman, a psychological thriller based on Alice Feeney’s novel, a twisty British thriller, a cat-and-mouse thriller, a Swedish crime writer solving mysteries with a detective, and more!

Plus, some bonus book recommendations!

Memory of a Killer by Jef Geeraerts

This new series is inspired by a Belgium thriller film, De zaak Alzheimer, or The Alzheimer Case/The Memory of a Killer, which is an adaptation of the same titled novel by Jef Geeraerts. The book, about a retired hitman with Alzheimer’s who takes one last job, has not been translated to English yet.

Memory of a Killer will premiere on January 26th (at 9/8c) on Fox and stream the following day on Hulu . The series follows Angelo Doyle who has early onset Alzheimer’s. His diagnosis makes it more likely that his entire world as a family man can come crumbling down because he’s secretly a hit man. The new series stars Patrick Dempsey and Gina Torres.

You can watch the trailer here.

Bonus book recommendations: For an Italian procedural series where the detective is hiding her recent symptoms of Alzheimer’s, pick up Flowers Over the Inferno by Ilaria Tuti, Ekin Oklap (translator). And for a South Korean crime novel centering an older hitwoman who discovers what happens when you reach the age of retirement, pick up The Old Woman With the Knife by Gu Byeong-mo, Chi-Young Kim (translator).
