probably murder on the orient express by agatha christie? I just love the closed-off luxury night-train as a setting, very entertaining and well-written, didn't see the end coming ❤️ the 2017 film doesn't do the book justice tho :(
Therapeutically dry entertainment. Long episodes, pleasant scenery. Nice that it takes place in the 30s- underrepresented era on television. David Suchet is great.
