Easy-peasy, thoroughly enjoyable Agatha Christie story. Charles Laughton is an unforgettable powerhouse and is perfectly cast for his character. You can’t get your eyes off him. He plays Sir Wilfrid, an upper-class twit version of Gary Oldman’s Jackson Lamb in Slow Horses. Made me wish Christie wrote more stories with his character.
It’s also a big, indulgent celebration of Britishness and the country’s Justice System (just noting; feature, not bug).
