What Happens in The Unguarded Hour: Full Plot Summary

The whole story of The Unguarded Hour (1936) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Barrister Sir Alan Dearden Franchot Tone is tipped to be Britain's next and youngest ever Attorney General. Shortly before he leaves for holiday on the Continent, his wife Lady Helen Dearden Loretta Young is approached by a man claiming to have love letters written by her husband to his own estranged wife. Although these pre-date their marriage, Lady Helen worries that scandal would ruin her husband's career and reluctantly agrees to pay the blackmail demand of £2,000. The following day, she draws the money out of the bank and meets the blackmailer in Dover, eventually leaving the money on the White Cliffs. While she is recovering the love letters, she sees a middle-aged man warning his wife not to go too near the edge.

She is enjoying her holiday with her husband when he is urgently called back to London to take over a murder case at the Old Bailey. A man named Samuel Metford Dudley Digges stands accused of pushing his wife over a cliff. A shocked Helen realises that she is the key witness in the case but elects to remain silent. During cross-examination, Dearden hounds Metford over his claims that there was a female witness who saw him warning his wife to take care by pointing out a nationwide hunt has not produced this supposed witness. Helen does what she can to persuade her husband that Metford is innocent and that people often make poor witnesses when they are telling the truth, but he is unmoved.

Then, during the trial, Dearden is approached by his former flame — Diana Roggers Aileen Pringle — encouraged by her estranged husband — who demands blackmail money from him. When shortly afterwards she is found murdered, Scotland Yard investigate and find suspicion is pointed at Dearden. While he has a genuine excuse of how she spent the "unguarded hour", his story sounds as unbelievable as Metford's.

In a sensational development, Lady Helen is subpoenaed by the defence in order to clear the accused, which she does. She then manages to entrap the original blackmailer into revealing that he was the man who killed Samuel Metford’s wife Dudley Digges.

The Unguarded Hour Plot Explained: Your Questions Answered

The questions people ask most about The Unguarded Hour (1936): what happens in the confusing scenes, why the characters do what they do, the twists, hidden details and what the ending means. Each answer contains spoilers.

Q1

Why does Lady Helen pay the blackmailer instead of telling her husband?

Lady Helen pays the blackmailer because she fears the love letters (written by Dearden to his estranged wife before their marriage) would ruin his political career. As the future Attorney General, any scandal could destroy his chances. She chooses to protect his reputation by paying £2,000 rather than risk exposing the affair.

  • love letters
  • blackmail
  • political career
  • Helen Dearden
Q2

Why does Lady Helen stay silent during the murder trial?

Lady Helen remains silent because she realizes she is the key witness who saw a man warning his wife not to go near the edge of the cliff, the same event Metford claims happened. However, testifying would reveal her visit to Dover and the blackmail payment, which could destroy her husband's career and expose her own involvement.

Foreshadowing: Earlier, she notices a middle-aged man warning his wife not to go too near the edge while on the White Cliffs.

  • witness
  • silence
  • trial
  • Metford
  • cliff
Q3

What is the "unguarded hour" that Dearden mentions?

The unguarded hour refers to the time period when Dearden's former flame Diana Roggers was murdered. He claims he was with her during this hour, but her husband had encouraged her to blackmail Dearden, making his alibi seem fabricated and unbelievable to investigators.

  • alibi
  • Diana Roggers
  • murder
  • Scotland Yard
Q4

How does Lady Helen prove Samuel Metford is innocent?

Lady Helen is subpoenaed by the defense and testifies that she witnessed the real event, a man warning his wife to stay away from the cliff edge, which contradicts the prosecution's theory that Metford pushed her. Her testimony directly contradicts Dearden's aggressive cross-examination and clears Metford.

  • testimony
  • Metford
  • innocent
  • defense
Q5

Who actually killed Samuel Metford's wife?

The original blackmailer who approached Lady Helen is revealed to be the actual killer of Metford's wife. He murdered her to prevent her from identifying him as the blackmailer, framing Metford for the crime.

  • murderer
  • blackmailer
  • Metford
  • wife
Q6

Why does the blackmailer target the Deardens specifically?

The blackmailer targets Dearden because he possesses love letters written by Dearden to his estranged wife before the marriage. Knowing Dearden's political ambitions, the blackmailer calculates that Helen would pay to protect his career rather than risk exposure.

  • blackmail
  • love letters
  • Dearden
  • political
Q7

What happens to Dearden after Diana Roggers is murdered?

After Diana Roggers is found murdered, Scotland Yard investigates and suspicion falls on Dearden. Though he has an alibi for the unguarded hour, his story sounds unconvincing given his prior encounter with the blackmailing couple, putting his reputation and freedom in serious jeopardy.

  • suspect
  • Scotland Yard
  • Diana Roggers
  • investigation
Q8

Why does Lady Helen change her mind and decide to testify?

Lady Helen decides to testify after being subpoenaed by the defense, but her motivation shifts when she realizes she can use the testimony to entrap the original blackmailer. Rather than simply clearing Metford, she orchestrates a confrontation that forces the blackmailer to admit to the murder.

  • testify
  • subpoena
  • blackmailer
  • entrapment
Q9

How does the murder trial connect to the original blackmail plot?

The two plots intersect when Lady Helen realizes she witnessed the real killer during her meeting with the blackmailer on the White Cliffs. The same man she saw warning his wife not to go near the edge is the person she later tries to help clear through her testimony, revealing the blackmailer's true role in the murder.

Foreshadowing: While returning from leaving the money, she sees a middle-aged man warning his wife not to go too near the edge.

  • connection
  • blackmail
  • murder
  • witness
Q10

Why does Diana Roggers blackmail Dearden during the trial?

Diana Roggers, Dearden's former flame, is encouraged by her estranged husband to confront Dearden for blackmail money. This creates a parallel to the main blackmail plot, personal secrets being used against Dearden while he prosecutes a case where witness credibility is central.
