Bobby Jones's morphia poisoning

Bobby Jones's morphia poisoning turns an apparently local investigation into a direct threat against its investigator. Someone puts morphia in his beer while he is asleep; the dose is reported as eight grains, yet he survives. The attack is initially unexplained, but later evidence identifies Moira Nicholson as the person who administered it and reveals why Bobby had become a target: his memory of the name Evans risked uncovering the fraud surrounding Alan Carstairs's death and John Savage's estate.

Causes and Motive

The poisoning follows a sequence of events that makes Bobby a liability to the conspirators. After the inquest, the Caymans ask whether Alan Carstairs, whose body has been identified as that of Amelia Cayman's brother, said anything before dying. Bobby first tells them no, then remembers that the dying man mentioned Evans. He writes to the Caymans with this information. A few days later, a letter offers him a job in Peru or elsewhere in South America. When he declines, the attempt on his life follows.

At first, Bobby and Frankie Derwent connect the attack to the possibility that Alan Carstairs was murdered. They reason that the people responsible might fear what Bobby saw or remembered, especially because his evidence could challenge the identification of the body. The poisoning does not, on its own, prove who killed Carstairs or explain the entire plot; it does make the danger surrounding the investigation concrete. The progression from a tempting job offer to a poisoned drink suggests an effort first to remove Bobby from the inquiry and then, when that fails, to silence him.

The explanation eventually comes through Roger Bassington-ffrench's account of the scheme. He says that Moira insisted Bobby must be put out of the way and that she went to Marchbolt, found her opportunity, and slipped morphia into his beer while he slept. The attack was therefore not merely a suspicious coincidence associated with the earlier death. It was a deliberate effort by the conspirators to prevent Bobby's recollection from leading investigators to Evans and the deception built around Alan Carstairs's identity.

The Attack and Bobby's Recovery

Bobby is found asleep and cannot be roused. Alarmed, those who discover him carry him to a farmhouse and call a doctor. At first, people suspect that he has taken the drug deliberately. The remains of the beer bottle he had discarded are then found and analysed; its dregs are sufficient to establish that the drink contained morphia. The pub where Bobby bought the beer is questioned, and other bottles are opened. Nothing is found wrong with them, supporting the conclusion that the drug was introduced into Bobby's own bottle after he had bought it.

The bottle's paper seal had not remained properly attached, a small irregularity that helps explain how it could have been tampered with. Bobby recalls being asleep when the opportunity arose, and the investigation establishes that the source was not a generally contaminated supply at the pub. The evidence points instead to someone who could approach his drink without attracting notice. The book later supplies the identity of that person through Roger's confession, rather than through the bottle analysis alone.

Bobby survives what he estimates to be eight grains of morphia. During his recovery, he makes a comic spectacle of the medical attention, announcing that he may become famous and recounting the amount he took with self-satisfied relish. Frankie cuts short his enthusiasm for the subject, but his joking also emphasizes the startling outcome: the intended victim is alive and able to continue investigating. His survival frustrates the plot against him and leaves the conspirators facing the very witness they had hoped to remove.

Evidence and Changing Interpretations

The poisoning changes the status of Bobby's suspicions. Before it, the possibility that Alan Carstairs had been pushed from the cliff is an inference assembled from uncertain clues, including the substituted photograph used to identify the body. After Bobby is attacked, Frankie argues that someone has a reason to get him out of the way, though neither she nor Bobby initially knows the assailant's identity. Bobby resists treating the poisoning as proof of every part of their theory. He points out that no one could have predicted that he would miss the newspaper report and fail to challenge the photograph immediately, and he questions whether the suspected Roger could have arranged the photograph substitution as they imagine. The poisoning intensifies the mystery without making every deduction certain.

Bobby and Frankie also establish that the morphia was not simply a random substance in an otherwise ordinary bottle. The bottle had been tampered with while he was asleep, and the unopened bottles checked at the pub were clear. Those facts establish the method and opportunity in broad terms, but they do not reveal the person who acted. Later, when Moira meets Bobby and presents herself as someone threatened by her husband, he has not yet understood that her account is part of the deception. Her apparent fear and the attack on Bobby occupy different places in his developing picture of the case until Roger's disclosure joins them.

Connection to the Wider Plot

The drug links Bobby's attempted murder to the scheme at the Grange. Roger explains that he had introduced Henry Bassington-ffrench to morphia, after which Henry became dependent on it. The plan was to send Henry to the Grange for treatment and have Moira arrange his death there, making it appear that he had taken an overdose or killed himself. Against that background, morphia is not just a means of attacking Bobby: it is also a substance used in a longer pattern of manipulation, concealment, and attempted control.

The poisoning also exposes the limitations of the conspirators' methods. Moira recognizes Bobby from the earlier occasion when she had seen him asleep, but after encountering him again she pretends to be frightened of Dr Jasper Nicholson and claims that Alan Carstairs was an old lover. She gives Bobby a misleading account while working to divert his suspicions from Roger. Her performance exploits the uncertainty created by the attack: Bobby knows someone has tried to kill him but does not yet know which of the people around him is responsible.

As a turning point in the investigation, Bobby's survival preserves the witness whose recollection can connect Evans to the false identification and the forged-will plot. The attempt fails not because the conspirators abandon their design, but because the intended victim recovers and continues to ask questions. Its later explanation reverses the apparent roles of victim and protector in Moira's story and makes the poisoned beer one of the clearest signs that the inquiry has reached the criminal network itself.
