Poirot investigates a series of killings in "The ABC Murders" in this excellent adaptation. As Hastings reappears after an absence, Poirot receives letters from a serial killer, calling himself ABC, who tells Poirot the city where the next murder will take place. At the scene of each crime, he leaves the ABC railroad schedule. The murders seem to have the same last name initial as the name of the town.
The authorities think the killer is insane, but Poirot doesn't. He believes there is a real method to the killer's madness. It takes a while, but Poirot finally figures it out.
Wonderful, exciting adaptation, and if you haven't read the book (or like me read it a hundred years ago) it's even more thrilling since you won't know the solution.
I love Poirot, Hastings, and Japp together. Suchet is so perfect as Poirot except for one small thing. Agatha Christie came to hate Poirot. There's no way she would have hated THIS Poirot. She found him "insufferable" and an "egocentric creep." Despite being fussy, egomaniacal, and arrogant, Suchet somehow gives Poirot warmth and a camaraderie with Japp and Hastings. I just love his interpretation. You can't hate him.
