‘Agatha Christie's Seven Dials’: More mystery thrillers based on books to watch on OTT

If you’re into classic whodunits, sharp detective work, or just love a story that keeps you guessing, ‘Agatha Christie’s Seven Dials’ is probably already on your radar. This new limited series drops you right into 1925 England — think fancy country house, a party gone wrong, and a curious young aristocrat who won’t let a murder go unsolved. Christie’s influence? It’s everywhere. Her books have inspired loads of other mystery thrillers, and now you can stream a bunch of them from your couch. Whether you’re after moody detective dramas, psychological puzzles, or just want to lose yourself in a tangled plot, there’s a whole stack of book-based mysteries waiting for you online. Here’s a look at seven such binge-worthy options for a weekend marathon or late-night deep dive.

You can’t talk about Christie and mystery thrillers without mentioning ‘Murder on the Orient Express’. This story’s had more than one adaptation, but the 2017 film really pops on screen. Picture this: a glamorous train, a murder, and Hercule Poirot trying to crack the case while every passenger looks guilty. The closed setting, the clever twists — this one never gets old.

It’s available on multiple OTT platforms, including Disney+ Hotstar.

Based on Stieg Larsson’s hit novel, ‘The Girl with the Dragon Tattoo’ throws together a relentless journalist and a brilliant hacker to dig up secrets that refuse to stay buried. It’s gritty, a little dark, and packed with psychological layers. If you like your mysteries with edge and depth, don’t skip this one.

It’s available for streaming on Netflix.

Eleven’s era has closed its chapter. But Millie Bobby Brown lights up the screen as ‘Enola Holmes’, Sherlock’s younger — and just as sharp — sister. Pulled from Nancy Springer’s books, this film is bright, witty, and full of clever detective work. It’s a fresher, younger spin on the classic mystery, but still pays respect to the original vibe.

You can stream it on Netflix.

Holly Jackson’s bestseller comes alive in this British series. Pip Fitz-Amobi, a determined teenager, reopens an old murder case for a school project and quickly finds herself in way over her head. Secrets, twists, and plenty of small-town drama make this six-parter a must for anyone who likes their mysteries with a little emotional punch.

Here’s a darker one. Amy Adams plays an agoraphobic woman convinced she’s seen a crime in the house next door. The more she digs, the more reality slips away. Based on A.J. Finn’s novel, this adaptation is all about mood and suspense — and it’ll keep you second-guessing until the credits roll.

It’s available on Netflix.

Louise Penny’s books set the stage for this series, which follows Chief Inspector Armand Gamache as he digs into dark secrets in a quiet Quebec village.
