Chapter 6
III: Piecing It Together
Mordaunt Reeves and Gordon Davenant meet in Reeves' room at the Paston Oatvile dormy-house to analyze the evidence. They debate whether the dead man is S. Brotherhood, discuss the possibility of murder versus suicide, and examine the anonymous letter containing a series of numbers. Reeves deduces it is a book cipher, with each triplet representing page, line, and word. They also consider a torn shopping list, the railway ticket, and the handkerchief found with the body. Reeves plans to investigate Brotherhood's bungalow, while Gordon will follow up on the Masterman clue.
Chapter 7
IV: Endless Clues
Mordaunt Reeves and Gordon begin their independent investigations into the death of the man believed to be Brotherhood. Reeves interviews Mrs. Bramston, the housekeeper, who provides little useful information despite her verbosity. Gordon visits Binver and retrieves handkerchiefs from the laundry, including one marked 'Brotherhood,' suggesting a possible connection. Carmichael later reports that Brotherhood was insured by an American company, adding a new layer of suspicion.
Chapter 8
V: On the Railway
Reeves and Gordon investigate the railway embankment where Brotherhood fell, discussing the murder theory and the difficulty of reconstructing the scene in clear weather.

Later, they board a train to Binver, where Reeves retrieves a book left behind, hoping it contains a cipher message, but the decoded text is nonsensical.
Chapter 9
VI: The Movements of Mr. Davenant
Gordon, Reeves, Marryatt, and Carmichael discuss the murder and the character of Davenant. Carmichael reveals that Brotherhood and Davenant are the same person. Gordon investigates Davenant's cottage, finding evidence that Davenant left on Monday with all his belongings, including soap and a photograph, suggesting a premeditated departure. He is nearly caught by Sullivan but manages to escape.
Chapter 10
VII: Carmichael’s Account of It
Carmichael reveals that Brotherhood and Davenant were the same person, a double identity maintained for years to facilitate a planned disappearance after bankruptcy. He explains the careful preparations, including separate banking, typewritten correspondence, and the deliberate contrast in golf skill and religious views. The chapter concludes that the murder must have been committed by a third party, as the original plan was interrupted by an unforeseen counterplot.
Chapter 11
VIII: The Inquest, and a Fresh Clue
The inquest into Brotherhood's death is held, resulting in a verdict of suicide while of unsound mind. Reeves, Gordon, Carmichael, and Marryatt discuss the case afterward.

Later, while playing bridge in Reeves' room, the photograph appears to change expression, unsettling the men and sparking a discussion about collective hallucination and the uncanny.
Chapter 13
X: In Which a Book Is More Communicative Than a Lady
Mordaunt Reeves visits Miss Rendall-Smith with the photograph found on Brotherhood's body, but she reacts defensively and dismisses his inquiries. Meanwhile, Carmichael discovers that the cipher key was a copy of Momerie's 'Immortality' left on a train, but when they attempt to decode the message, the cipher itself has vanished from Reeves' room. They successfully decode the message from memory using a marked book, revealing the warning: 'You will perish if you go back upon your faith.' Carmichael hints that the cipher's disappearance is itself a significant clue.
Chapter 14
XI: A Funeral and a Vigil
After Brotherhood's funeral, Carmichael reveals that a cipher document was taken from Reeves' room and then returned, indicating someone is spying on them. He proposes setting a trap by posting a notice about Brotherhood's souvenirs to lure the intruder. Reeves and Gordon agree to keep watch outside the room that night.
Chapter 15
XII: A Search with Piano Accompaniment
Carmichael reveals that he locked Reeves' room the previous night to trick the intruder into entering through a hidden passage. With Reeves playing piano loudly as cover, Carmichael and Gordon search the room for secret panels, eventually discovering a sliding panel in the cornice that leads to a priest's hiding place.
Chapter 16
XIII: The Man in the Passage
Gordon, Carmichael, and Reeves discover a secret passage in Reeves' room and plan to investigate it. They find the other end in the billiard-room, where a game appears to have been interrupted.

They emerge to find a policeman waiting in Reeves' room.
Chapter 17
XIV: A Chase, Ending with a Surprise
Reeves and Gordon, while investigating a secret passage, are confronted by a police sergeant who is also pursuing the murderer.

Chapter 18
Gordon Takes the Opportunity to Philosophize
Carmichael, Reeves, and Gordon discuss the implications of their mistaken theory that Davenant and Brotherhood were the same person.

Chapter 19
XVI: Reeves Promises to Do His Best
Reeves meets with Miss Rendall-Smith, who reveals she is actually Mrs. Brotherhood, the widow of the murdered man.

She asks Reeves to investigate and prove Davenant's innocence, trusting his detective abilities.
Chapter 20
By Which Train?
Reeves and Gordon debate the evidence against Davenant, focusing on the incongruities of the ticket and watches found on Brotherhood's body. They develop a theory that the murder was timed to mislead investigators about which train Brotherhood traveled on, suggesting the killer manipulated the evidence.
Chapter 21
XVIII: The Holmes Method
Gordon, Reeves, and Carmichael investigate the disappearance of the book containing the cipher. Carmichael uses deductive reasoning to deduce the physical characteristics of the thief from the arrangement of books and a used pipe-cleaner. Gordon and Reeves debate the plausibility of their theories about the murder, focusing on how Davenant could have known about Brotherhood's death and how the book ended up on the train.
Chapter 22
XIX: Mordaunt Reeves Talks to Himself
Mordaunt Reeves, alone in his armchair, struggles to piece together the clues of the murder, fixating on a golf ball found by the railway line. He takes a walk to the embankment, imagining himself as a passenger on the train to reconstruct the crime. Later, he visits Paston Oatvile churchyard, where he overhears Marryatt delivering a sermon on Brotherhood's sudden death. Reeves then retrieves a hidden walking stick, which he smuggles to his room, and later visits Miss Rendall-Smith, who shares her suspicion that she is being watched by a stranger.
Chapter 23
Proof at Last
Reeves reveals to Gordon that he has solved the murder, identifying Marryatt as the killer. He presents a chain of circumstantial evidence: Marryatt took the Momerie book from Reeves' room, gave it to Brotherhood, sent a theological cipher message, traveled on the 3:00 train to establish an alibi, behaved suspiciously after the body was found, and lied about knowing Miss Rendall-Smith. Reeves proposes a test using the walking stick to confront Marryatt.
Chapter 24
XXI: The Test
Reeves and Gordon set a trap for Marryatt by tampering with his pipes and hiding in the secret passage. When Marryatt returns to his room and sees the oaken cudgel, he reacts with terror, confirming Reeves' suspicions. Gordon overhears Marryatt crying out in distress, and they debate what to do next.
Chapter 25
XXII: In the Fog
Reeves, speaking through a tube to Marryatt, meticulously reconstructs the murder of Brotherhood, detailing how Marryatt used the fog, a golf ball, and a heavy stick to kill him on the train at the viaduct, then attempted to stage it as a suicide. Reeves reveals that an innocent man, Davenant, is awaiting trial for the crime and demands a full confession.
Chapter 26
Marryatt Breaks the Pledge
Reeves learns that Davenant has confessed to murdering Brotherhood, and that Marryatt, after being told via speaking tube, has fled to London. Gordon and Reeves discuss the situation, and later Marryatt returns, explaining he fled due to a combination of seeing Brotherhood's stick in Reeves' room and hearing a voice on the tube that he thought said 'Brotherhood.' Gordon reveals the stick was found on the railway line and that he and Reeves were in the secret passage, causing the breathing Marryatt heard.
Chapter 27
Gordon Offers the Consolation of Philosophy
Gordon explains to Reeves that Marryatt was not listening on the metaphone, and that the entire suspicion was based on a chain of coincidences. He argues that Marryatt is not the type to commit murder, contrasting him with Davenant, and uses the situation to critique historical and critical methods that rely on selective evidence and ignore human probabilities.
Chapter 28
The Dull Facts
Carmichael writes to Gordon summarizing the resolution of the Links Mystery. He details how Davenant followed Brotherhood on the day of the murder, the events at the station and the walk through the fog, and the various clues that misled the investigation. He also explains the cipher acrostic, the sleeper-coupon error, and the roles of Miss Rendall-Smith and Marryatt. The letter concludes with observations about Reeves' transformation and lingering questions about Miss Rendall-Smith's involvement.
