🍿 Green for Danger: Detailed Plot Synopsis
The Mysterious Death
During the Blitz in WWII England, a postman named Joseph Higgins is admitted to Heron’s Park Hospital after being injured by a V-1 bomb. While undergoing a relatively minor surgery, he unexpectedly dies on the operating table. The attending staff includes surgeon Mr. Eden, anesthetist Dr. Barnes, and nurses Linley, Sanson, and Woods. The death is initially deemed accidental, but suspicion soon arises.

A Nurse’s Accusation and Subsequent Murder
Sister Bates, one of the nurses present during Higgins’ surgery, publicly announces at a hospital social event that she believes Higgins was murdered and claims to possess evidence. Later that night, she is found stabbed to death in the operating theatre. This confirms the suspicion of foul play and brings Inspector Cockrill of Scotland Yard into the investigation. The pressure rises as the remaining staff become prime suspects.

Inspector Cockrill’s Investigation
Inspector Cockrill, a wry and unconventional detective, arrives at Heron’s Park to investigate the two deaths. He interviews each member of the hospital staff, uncovering personal secrets, romantic entanglements, and professional rivalries. Dr. Barnes, already haunted by a past incident of a patient dying under anesthesia, becomes a major suspect. As Cockrill digs deeper, he discovers that the missing poisonous pills and the theatre atmosphere contribute to the mystery.

💥 Green for Danger Reviews
Personal Review
I really enjoyed this movie! It felt like a classic Agatha Christie novel come to life. Alastair Sim is brilliant as Inspector Cockrill; he really steals every scene he’s in. The scene where Nurse Bates announces she knows the murderer is so tense, and the second murder is genuinely creepy, with shadows and wind. I was guessing until the very end, and the twist was great!

Professional Reviews
- The Film Stage: “A rare treat with the incomparable Alastair Sim as Cockrill. The plot is a convoluted murder mystery in which five people have motive and means to commit murder — but whodunit? It’s a bit stodgy but lots of fun.
- Indiewire: “A bravura example of simplicity in the art of movie making…it also has the gorgon-eyed brilliance of Alistair Sim: a man late to his profession but BOY did he make up for it! Check out his delivery in this film and his constantly out-of-kilter (and surely spontaneous) body language.
- N/A: “The acting (though a tad stiff) is dead on the ball; the dialogue is always precise and frequently ingenious (Sim’s music hall gag about impurities…); the editing is never less than effective and the direction and cinematography constantly inspired.
Audience Reactions
Alastair Sim’s performance as Inspector Cockrill is considered as the best part of the movie.: The film is praised for its classic British charm, witty dialogue, and suspenseful plot.
The setting during the WWII London Blitz adds to the atmosphere.: Many viewers enjoyed the twists and turns of the mystery, although some found the initial plot setup confusing.
