The Book in Brief
Oliver Whyte is chloroformed to death in a Melbourne hansom cab. Detective Gorby follows witnesses and timing to Brian Fitzgerald, Whyte's rival for Madge Frettlby, and arrests him. Brian refuses to reveal that he spent the crucial time with a dying woman because her story concerns Madge's father. Barrister Duncan Calton and detective Kilsip locate Sal Rawlins, who proves Brian's alibi at trial and secures his acquittal, but the murderer remains free.
The dead woman was Rosanna Moore, Mark Frettlby's lawful first wife. Their daughter is Sal Rawlins, which makes Madge's legitimacy doubtful. Whyte held the marriage certificate and used it to force Frettlby toward allowing his marriage to Madge. Frettlby followed Whyte on the murder night and later paid Roger Moreland for silence, making Brian and Calton initially believe Frettlby was the killer. Frettlby's written confession instead reveals that Moreland admitted chloroforming Whyte to steal the certificate and blackmail Frettlby. Kilsip traps Moreland into a direct admission; Moreland is arrested and hangs himself. The survivors burn Frettlby's confession, provide for Sal without telling her parentage, and allow Madge and Brian to marry and leave Australia.

Chapter-by-Chapter Summary
Chapter 1: What the Argus Said
A newspaper account reconstructs how an intoxicated man entered a Melbourne hansom with another gentleman and was found dead at the destination. The unknown companion disappeared, leaving police with a chloroform murder in a moving cab.
Chapter 2: The Evidence at the Inquest
Cabmen, police, and Dr. Chinston testify about the dead passenger, the second man's movements, and the chloroformed handkerchief. The jury finds willful murder by an unknown person, but the victim has not yet been formally identified.
Chapter 3: One Hundred Pounds Reward
The government publishes a reward notice describing the dead man and the suspected companion. The brief official document turns the mystery into a public search for identity and evidence.
Chapter 4: Mr. Gorby Makes a Start
Detective Gorby reasons through the timing, clothing, poison, and a roughly sewn secret pocket in the victim's waistcoat. He decides to identify the dead man through his lodging and begins with the St Kilda address.
Chapter 5: Mrs. Hableton Unbosoms Herself
Whyte's landlady identifies him and describes his associates, especially Roger Moreland and Brian Fitzgerald. She also reports Brian's public threat against Whyte over Madge, leading Gorby to place a woman at the center of the motive.
Chapter 6: Mr. Gorby Makes Further Discoveries
Gorby questions Moreland about Whyte's final days and his rivalry with Brian. Moreland encourages suspicion of Fitzgerald while presenting himself as a grieving friend, and Gorby quietly continues building the case.
Chapter 7: The Wool King
The narrative introduces wealthy Mark Frettlby, his daughter Madge, Brian, and their social circle. Madge and Brian are engaged despite Whyte's earlier pursuit of her, establishing the romantic and financial stakes behind the murder.
Chapter 8: Brian Takes a Walk and a Drive
Gorby shadows Brian, who travels through Melbourne and revisits places connected with the murder. The detective compares Brian's movements with the cab timeline and prepares to test his lodging-house alibi.
Chapter 9: Mr. Gorby Is Satisfied at Last
Brian's landlady gives Gorby a return time that appears to fit the murder and shows him Madge's photograph in Brian's rooms. Gorby decides the accumulated motive, threat, identification, and timing justify an arrest.
Chapter 10: In the Queen's Name
Police arrest Brian in front of Madge and Frettlby. Brian offers no public explanation, while Madge immediately declares her loyalty and collapses under the shock.
Chapter 11: Counsel for the Prisoner
Calton interviews Brian in jail and recognizes that he is protecting the identity of someone who can prove an alibi. Brian still refuses to speak, and Calton concludes that his client knows a crucial secret even though he did not commit the crime.
Chapter 12: She Was a True Woman
Madge visits Brian and promises to save him regardless of the scandal attached to his silence. Her loyalty persuades Calton to search independently for the woman Brian is protecting.
Chapter 13: Madge Makes a Discovery
Madge and Calton search Brian's rooms and recover part of a burned letter summoning him on the murder night. The fragment supplies a path toward the hidden alibi and the woman who wrote it.
Chapter 14: Another Richmond in the Field
Calton enlists Detective Kilsip, Gorby's professional rival, to trace the burned letter. Their inquiry leads toward Mother Guttersnipe and a recently deceased woman known as the Queen.
Chapter 15: A Woman of the People
Calton and Kilsip visit Mother Guttersnipe in the Melbourne slums and learn that the dead woman possessed papers stolen from a wealthy villa. They identify Sal Rawlins as the witness most likely to prove where Brian spent the missing time.
Chapter 16: Missing
Sal cannot be found, and the defense uses advertisements and police contacts to search for her. With Brian still refusing to betray the dead woman's confidence, the approaching trial threatens to begin without his decisive witness.
Chapter 17: The Trial
The prosecution presents the cab evidence, threats, coat, ring, and lodging-house timing against Brian. Calton exposes a narrow timing problem in the case, and the proceedings end with news that Sal Rawlins has finally returned.
Chapter 18: Sal Rawlins Tells All She Knows
Calton questions Sal and confirms that Brian spent the critical period with the dying woman rather than in the cab. Her account explains his silence and gives the defense a witness capable of breaking Gorby's chronology.
Chapter 19: The Verdict of the Jury
Sal testifies that Brian remained with her at the necessary time, making his presence in the murder cab impossible. The jury acquits him, and he is reunited with Madge, but the identity of Whyte's killer remains unresolved.
Chapter 20: The Argus Gives Its Opinion
The newspaper praises the acquittal while arguing that the real murderer sought papers hidden on Whyte's body. It calls for investigators to trace the dead woman and the document, accurately redirecting attention toward the buried motive.
Chapter 21: Three Months Afterwards
Brian remains troubled by the secret Rosanna revealed before death while life resumes at the Frettlby estate. Sal's presence and questions about Rosanna bring the concealed first marriage closer to Madge.
Chapter 22: A Daughter of Eve
Brian tells Madge that he carries a secret capable of damaging both their lives but still cannot disclose it. Frettlby's arrival forces the couple to maintain appearances while Brian watches him for signs of guilt.
Chapter 23: Across the Walnuts and the Wine
A country-house dinner mixes political and social talk with guarded questions about Frettlby's past. Brian's questions about Rosanna make Frettlby visibly uneasy and strengthen Brian's suspicion.
Chapter 24: Brian Receives a Letter
Calton writes that Rosanna Moore was Frettlby's lawful first wife and returned to Melbourne with proof of the marriage. The discovery explains Whyte's leverage and why the stolen paper mattered enough to provoke murder.
Chapter 25: What Dr. Chinston Said
Brian plans to leave rather than continue deceiving Madge, while Dr. Chinston warns that Frettlby's heart may fail under a sudden shock. The medical warning raises the cost of confronting him directly.
Chapter 26: Kilsip Has a Theory of His Own
Kilsip tells Calton that Roger Moreland's possession of Whyte's coat and knowledge of the chloroform make him more suspicious than the accepted story suggests. Calton remains doubtful but agrees the evidence deserves testing.
Chapter 27: Mother Guttersnipe Joins the Majority
Calton and Kilsip revisit Mother Guttersnipe as she dies. Her disclosures establish that Rosanna was Frettlby's wife and that Sal Rawlins is their daughter, making Madge's legitimacy and inheritance morally complicated.
Chapter 28: Mark Frettlby Has a Visitor
Roger Moreland visits Frettlby for money, and Brian recognizes him leaving the house. Madge sees that Moreland's presence terrifies her father, while Frettlby realizes the blackmailer can control his reputation indefinitely.
Chapter 29: Mr. Calton's Curiosity Is Satisfied
Brian tells Calton about Frettlby's first marriage and assumes Frettlby killed Whyte to recover the certificate. A message reporting Frettlby's sudden death interrupts their conclusion before it can be tested.
Chapter 30: Nemesis
Frettlby writes a full confession of his past and seals it in his desk. Madge glimpses the marriage document during the crisis, and the emotional shock ends with Frettlby dead and his daughter unconscious.
Chapter 31: Hush-Money
Brian, Calton, and Chinston examine Frettlby's papers and find the confession and original marriage certificate. They also see evidence of a large payment to Moreland and debate the inheritance, Sal's status, and how much truth should be made public.
Chapter 32: De Mortuis Nil Nisi Bonum
Kilsip challenges Calton's belief that Frettlby committed the murder, producing Whyte's hidden coat with an empty chloroform bottle. The men agree to read Frettlby's confession before deciding whether to arrest Moreland.
Chapter 33: The Confession
Frettlby recounts marrying Rosanna, abandoning her after believing her dead, and later being blackmailed by Whyte with the certificate. He states that Moreland admitted killing Whyte for the document and then forced Frettlby to pay for silence.
Chapter 34: The Hands of Justice
Calton and Kilsip lure Moreland into discussing the money and confront him with the confession and coat. Moreland admits using Whyte's own chloroform to steal the certificate in the cab, believing at first that he had only rendered Whyte unconscious; he is arrested.
Chapter 35: The Love That Lives
Moreland hangs himself before trial, and the group burns Frettlby's confession rather than expose the full scandal. Sal receives an income without learning her parentage, Madge retains the estate, and she and Brian marry and sail from Australia.
Ending Explained
Who murdered Oliver Whyte? Roger Moreland. Wearing Whyte's coat, he enters the cab after the driver mistakes him for Brian, uses the chloroform from the coat to subdue Whyte, and steals the marriage certificate.
Why does Brian refuse his alibi? The dying Rosanna Moore entrusted him with the secret of her lawful marriage to Mark Frettlby. Revealing where he spent the night would expose Madge's family scandal.
What is Mark Frettlby's crime? He abandons Rosanna, permits Whyte to use the secret against the family, pays Moreland after learning of the murder, and suppresses the truth. He is morally compromised but is not Whyte's killer.
Who is Sal Rawlins? She is the daughter of Mark Frettlby and Rosanna Moore, and therefore Madge's half-sister. The surviving men conceal this fact while settling an income on her.
What happens to Moreland? After admitting the murder and being arrested, he hangs himself in his cell without leaving a confession.
Why is Frettlby's confession burned? Brian, Calton, Chinston, and Kilsip decide that publication would only disgrace Madge and expose Sal after the killer's death. The legal mystery is solved privately but never fully disclosed to the public.
Themes and Motifs
Public evidence and private truth The newspaper, inquest, and trial create official versions that are plausible but incomplete. The decisive truths remain in letters, memories, and private confessions.
Respectability as concealment Frettlby's wealth protects a history no less damaging than the crimes associated with the slums. Social position determines which secrets receive sympathy.
Loyalty versus justice Brian keeps silent to protect Rosanna and Madge even at the risk of the gallows, while the final group protects Frettlby's reputation after solving the case. The novel repeatedly treats silence as both noble and corrupt.
The city as evidence Routes, clocks, railway times, cab stands, and neighborhoods are essential to the deductions. Melbourne's geography makes and unmakes the case against Brian.
Inheritance and legitimacy The murder document threatens not only reputation but the legal and emotional identity of two daughters who did not create their father's wrongdoing.
Content Notes
Murder by chloroform, arrest, imprisonment, suicide by hanging, blackmail, alcoholism, terminal illness, and family abandonment.
The book contains classist portrayals of poor people, offensive dialect, and dated treatment of sex work, addiction, legitimacy, and mental illness.
The ending withholds Sal's parentage from her and frames that paternalistic decision as protective.
