Season 12

Poirot confronts staged performances and poisoned cocktails in Three Act Tragedy, follows Ariadne Oliver into a drowning at a Halloween party, and faces moral ambiguity in Murder on the Orient Express. By the time he investigates a baffling stabbing in The Clocks, it’s clear the mysteries are as much about conscience as crime.
