Lessons to borrow
- A mystery's solution can be hidden in plain sight by manipulating what people expect to see; Grodman's crime succeeds because he understands how prepossession blinds investigators and the public.
- Circumstantial evidence is unreliable and can convict the innocent; Wimp's case against Mortlake is built on motive and opportunity but lacks proof, showing how justice can fail through incomplete investigation.
- The perfect plan can be undone by chance and accident; Grodman's scientifically designed crime is ultimately defeated not by detective work but by random events like Mrs. Drabdump's oversleeping and the fog.

- Ch 5: quiet. Denzil leaves Wimp's office and gives his sovereign to a servant girl, then visits Grodman who cryptically says he can identify the murderer
Yes," said Grodman, "but you drink so much. (Ch 6, para 141)
- Ch 6: cliffhanger. Grodman announces he can lay his hand on the murderer now, and cryptically suggests Denzil will not live long enough to write the story
Yes," said Grodman, "but you drink so much. (Ch 6, para 141)

Grodman was busy thinking how to get at Wimp's domestic. (Ch 7, para 24)

Tom Mortlake, I arrest you for the murder of Arthur Constant! (Ch 8, para 65)

| 1 | Mrs. Drabdump discovers her lodger Arthur Constant dead in his locked bedroom with his throat cut, and calls the retired detective Grodman to help. | Mrs. Drabdump needs to wake Arthur Constant for an early meeting | Constant does not answer repeated calls; his door is locked and bolted from within | Grodman breaks down the door and finds Constant dead with a deep throat wound |
| 2 | The inquest hears evidence from Mrs. Drabdump, Tom Mortlake, Grodman, and police officials about the locked room and the impossible circumstances of Constant's death. | The coroner seeks to establish how Constant died and whether it was suicide or murder | The evidence shows the room was locked from within, yet the wound could not be self-inflicted | Multiple witnesses testify; the police find no weapon and no way anyone could have entered or left |
| 3 | The coroner sums up the evidence, concluding that the death was neither suicide nor murder, and the jury returns an open verdict. | The coroner must explain the evidence and guide the jury to a verdict | The facts seem to rule out both suicide and murder, leaving an impossible situation | The coroner declares the case incomprehensible; the jury returns an open verdict despite one juror's objection |
| 4 | The press and public become obsessed with the Big Bow Mystery, proposing wild theories, while Grodman writes a letter claiming he can solve it and calling for new information. | The public seeks to solve the mystery through speculation and theory | No satisfactory explanation emerges; theories are absurd or impossible | Grodman publicly announces he can identify the murderer and invites information |
| 5 | Denzil Cantercot, a struggling poet, visits Peter Crowl's cobbler shop, quarrels over unpaid rent, then seeks money by offering information to Detective Wimp about Tom Mortlake and the missing Jessie Dymond. | Denzil needs money and seeks to sell information about the mystery to Wimp | He must convince Wimp that his information about Mortlake and Jessie is valuable | Wimp pays him a sovereign and assigns a body-guard to follow him |
| 6 | Denzil struggles to find money, visits a plot-seller, then dines with the Crowls before going to Grodman's house where he learns Grodman has identified the murderer. | Denzil seeks to raise money and gather information about the mystery | He cannot find work or credit; Grodman refuses to pay him without work | Grodman cryptically reveals he knows who the murderer is |
| 7 | Grodman and Wimp dine at Christmas and spar over suspicions about Denzil Cantercot, while Grodman reveals he has discovered Denzil's alibi through his servant Jane. | Wimp wants to pump Grodman about Denzil; Grodman wants to unsettle Wimp | Each detective suspects the other's suspect and tries to extract information | Grodman reveals Denzil has an alibi, leaving Wimp frustrated and uncertain |
| 8 | Denzil returns after three days away looking disheveled, claiming he was working on a new paper; the unveiling ceremony of Constant's portrait approaches with Gladstone attending. | Denzil must explain his absence; Grodman and Wimp both prepare to make arrests | Denzil's story is vague and suspicious; both detectives are closing in on their suspects | Denzil attends the ceremony; Grodman and Wimp both position themselves to arrest him or Mortlake |
| 9 | Wimp arrests Mortlake at the ceremony, but Crowl and the crowd riot to protect him; Mortlake escapes in the darkness when Crowl turns off the gas. | Wimp wants to arrest Mortlake; the crowd wants to protect him | Wimp's dramatic arrest triggers a violent riot; Mortlake's supporters overwhelm the police | Mortlake escapes into darkness after Crowl cuts the gas; several rioters are arrested instead |
| 10 | Mortlake surrenders at a police station; the trial begins with Wimp presenting evidence of Mortlake's jealousy over Jessie Dymond and his access to Constant's room; the jury convicts him despite the defense's strong alibi arguments. | The prosecution must prove Mortlake murdered Constant; the defense must establish his innocence | Circumstantial evidence versus alibi; motive versus opportunity | The jury finds Mortlake guilty; the judge sentences him to death |
| 11 | Grodman reveals he was about to arrest Denzil for bigamy but forgave him when Wimp's case against Mortlake seemed strong; now Grodman leads a campaign to find Jessie Dymond and save Mortlake from execution. | Grodman wants to save Mortlake; the Home Secretary must decide whether to grant a reprieve | Time is running out; Jessie Dymond remains missing; the public demands justice or mercy | Grodman rushes to the Home Secretary with new evidence as the execution looms |
| 12 | Grodman confesses to the Home Secretary that he murdered Arthur Constant as a scientific experiment, then shoots himself when he learns the real evidence would have freed Mortlake anyway. | Grodman wants to confess his crime and explain his theory of evidence to save Mortlake from execution | The Home Secretary is impatient; Grodman's confession arrives just as a cable proves Mortlake's innocence; Grodman's perfect crime is undone by accident | Grodman confesses fully, the prisoner is reprieved, and Grodman shoots himself rather than face exposure |
