An Offer from Abroad

An Offer from Abroad
A sudden opportunity
Bobby receives an unusually generous job offer from Henriquez and Dallo, with an urgent request that he leave for South America. The unexplained recommendation and timing make the offer suspicious to Frankie.
A failed diversion
Bobby refuses because he has promised to join Badger’s garage business. His decision keeps him near the mystery and frustrates whoever hoped to remove him from the scene.
Poison in the Beer

Poison in the Beer
A second attack
While Bobby sleeps after a solitary picnic, someone puts morphia into his beer. He is found unconscious and taken to St Asaph’s after surviving a dose believed to be lethal.
The pattern becomes personal
The poisoning convinces Frankie that the cliff death and the attempted killing may be connected. Bobby’s survival turns him from a possible witness into an active investigator.
A Staged Entrance

A calculated crash
Frankie arranges a deliberate collision near Merroway Court and presents herself as an injured aristocratic visitor. Dr George Arbuthnot supports the deception by claiming to be a doctor and insisting she needs rest.
Entry to the household
The accident gains Frankie access to the home of Roger and Sylvia Bassington-ffrench. The fabricated mishap opens a new investigative front while exposing her to people she suspects.
A Threat from Within

A frightened visitor
Moira comes to Bobby at the Anglers’ Arms and says her husband means to kill her. She believes Dr Jasper Nicholson is arranging to have Henry sent to The Grange as part of a plan involving Sylvia.
A wider conspiracy
Bobby learns that Moira knew Alan Carstairs and had seen him after her marriage. Her disclosures connect the cliff victim to the household, though she does not yet reveal her own criminal role.
A Confession from Exile

A Confession from Exile
The scheme exposed
Roger writes from South America and admits his roles in John Savage’s fraudulent will, Alan Carstairs’s murder, and Henry’s staged suicide. He describes how Moira and the Caymans helped protect the crimes.
No settled justice
Roger says he is beginning life anew rather than claiming reform. His letter resolves the plot’s chief uncertainties but leaves the audience with an unsettlingly confident criminal beyond immediate reach.
