Impersonation and disguise of identity

Impersonation and disguise of identity are not incidental deceptions in the novel: they help the conspirators pursue John Savage’s fortune, conceal Alan Carstairs’s murder, and misdirect Bobby Jones and Frankie Derwent. The shifting identities make appearances unreliable, but they also leave practical traces—photographs, witnesses, and a servant’s knowledge—that allow the investigators to revise their theories.

Assumed Names and False Appearances

Moira Nicholson travels under various names because of complications in the drug business. As Mrs Templeton, she meets John Savage, having learned of his wealth and seeking to win his interest. Roger Bassington-ffrench later explains that Moira and her accomplices developed a plan involving Savage, with Leo Cayman playing the part of an unfeeling husband. Savage was induced to visit Tudor Cottage more than once; on his third visit, the conspirators carried out their scheme. Moira took the money and appeared to go abroad, but in fact returned to Staverley and The Grange.

The false identity was useful because it gave Moira access to Savage while concealing her connection to the wider group. The account makes the assumed name part of an organized criminal method, not simply an isolated social pretence. The apparent departure abroad likewise disguises where she has gone: her movements seem to remove her from the affair just as she returns to the place from which the conspiracy continues.

The Body and the Photograph

The identification of Alan Carstairs’s body is another deception built around substituted identity. After Bobby describes the Caymans and their identification of the corpse, Moira asks whether the body was really her brother’s or Alan Carstairs’s. Bobby recognizes that the identification is where the criminal work lies. Roger later explains that Carstairs had a photograph of Moira, apparently obtained from photographers to identify her. Roger removed it, along with letters and other identifying material, and planted a photograph of someone in the gang. The Caymans then came to identify the body as the supposed brother-in-law.

The photograph makes identity appear to be a matter of evidence while showing how evidence itself can be manipulated. Earlier, Bobby and Frankie reason that Roger may have replaced the photograph after Bobby returned the one he had seen to the dead man’s pocket. Bobby doubts the theory: he thinks Roger arrived several minutes after he put the photograph back, and he questions why the murderer would wait until after the inquest to eliminate a witness who might recognize the substitution. These objections keep suspicion from becoming proof. Roger’s later account confirms that the photograph and other identifying material were changed, while revealing how the misidentification helped conceal Carstairs’s real identity.

The Savage Will and a Borrowed Identity

Frankie’s explanation of the will scheme depends on the possibility that Roger impersonated John Savage. She notices that Mrs Templeton had summoned the gardener to witness the will even though a house-parlourmaid was present. Bobby discovers that the parlourmaid was Gladys Evans. Frankie reasons that Evans could have recognized that the man signing the will was not Savage, because a parlourmaid served guests at dinner and encountered them at close range, unlike a cook who might rarely see them. The choice of witnesses therefore looks less like a formality than a way to avoid a witness who knew the household’s visitor.

In Frankie’s reconstruction, Roger appeared as Savage before a lawyer who did not know Savage personally. The will’s other witnesses were also unlikely to identify the impostor: one had never seen Savage, and the elderly gardener might have been unable to recognize him. Frankie suspects that the real Savage was drugged and kept in the attic while Roger signed in his place, then returned to bed and given chloral. This sequence is her explanation of the evidence, not a directly witnessed account. She also suggests that an expert might identify the forged signature, although the signature had not previously been questioned because nobody had reason to suspect the will was false.

The scheme’s apparent legitimacy rests on more than the borrowed identity. Roger says that the charitable bequest was his idea because it made the will sound respectable. The respectable surface and the impersonation work together: the false Savage supplies the signature, while the will’s apparently plausible terms help discourage scrutiny. Gladys Evans’s absence from the witnessing process becomes the detail that breaks this arrangement open.

Deception as Misdirection

Roger’s impersonation of Dr Jasper Nicholson is a separate, deliberate trick. When Frankie asks why he pretended to be the doctor, Roger says he wanted to see whether he could deceive her and Bobby. They had become certain that Nicholson was involved because of his questioning about Frankie’s accident, which Roger describes as a consequence of Nicholson’s attention to detail. Nicholson was innocent; his manner had made him look like a criminal to the investigators, and Roger chose to sustain that mistaken impression for amusement and advantage.

Roger also describes how he learned that Frankie was not the unsuspecting young woman she appeared to be. He heard her chauffeur say her name during a telephone call, proposed traveling to London with her, and noticed her relief when he changed his mind. By posing as Nicholson and encouraging the investigators’ error, he turned their own suspicions into cover for himself. The disguise is therefore not only about claiming another person’s identity; it also involves performing the role that other people already expect to see.

What the Disguises Reveal

The impersonations repeatedly force Bobby and Frankie to distinguish observation from inference. In Marchbolt, they debate whether Roger could have changed the photograph and whether their theory explains the delay around the inquest. In the Savage investigation, Frankie moves from the unusual choice of a witness to the possibility that the signer was an impostor. In each case, a clue acquires meaning only when compared with what a particular person could have known or recognized.

The deceptions also connect crimes that might otherwise seem separate. Moira’s assumed identity brings her to Savage; the false identification of Carstairs protects the gang after his death; and the suspected impersonation at the will creates the appearance of a lawful transfer of Savage’s wealth. Roger’s false presentation as Dr Nicholson, meanwhile, demonstrates how easily a convincing appearance can redirect an investigation. Against these performances, Gladys Evans matters because she may have been able to recognize the real Savage. Identity in the plot is repeatedly staged for an audience, but the scheme becomes vulnerable wherever someone has the knowledge to tell the performance from the person.
