Poisoning of Gwen Chalmers

The Poisoning of Gwen Chalmers turns an ordinary package of chocolates into a decisive clue in the investigation. Seen first as an abrupt medical emergency in the apartment courtyard, the episode later becomes evidence against John Murphy: he had sent the poisoned sweets so Gwen would be too ill to swim. Its reversal matters as much as the poisoning itself. Mrs Bortz is the person shown handing Gwen the package, but that visible act does not establish that she sent it; the eventual account identifies Murphy as responsible.

The Courtyard Seen on Screen

The incident begins during the Investigators’ watch of the apartment courtyard through a television picture. They have waited for the courtyard lights to come on, and the view gives them a window onto residents’ movements. Sonny Elmquist appears and returns to his apartment with a laundry bag. Then a plump young blonde woman enters the foreground. Fenton Prentice identifies her as Gwen Chalmers.

Gwen is about to unlock her door when Mrs Bortz appears behind her and hands her a package. The camera records the exchange, not its explanation: at this point, neither the package’s contents nor its sender is established. The scene’s ordinary social gestures make the later emergency more startling. Gwen opens the package, smiles at what she finds, takes a chocolate, and eats it. She then takes another object from the box. Jupiter Jones identifies the contents as chocolates, while Fenton Prentice remarks on Gwen’s fondness for sweets. The observation initially makes the moment seem domestic and unremarkable, even as the viewing arrangement has placed it under close scrutiny.

Sudden Illness and Recognition

Gwen offers the candy box to Mrs Bortz, apparently remembering her manners, but the exchange is interrupted when she puts a hand to her throat. The box drops, scattering chocolates. Gwen lurches forward from her chair, bends over, and falls to the courtyard floor, where she writhes. The sequence moves quickly from eating to visible distress; the watching boys respond by rushing for the door and running downstairs.

By the time Jupiter reaches the courtyard, Gwen is crying, and John Murphy has come from his apartment to bend over her. Sonny Elmquist is also present, with his apartment door open. Mrs Bortz seizes Jupiter’s arm and shakes him, crushing a chocolate-covered candy in his hand. Jupiter smells the crushed sweet and immediately warns that something in it should not be there and that Gwen may have been poisoned. His recognition shifts the episode from an unexplained collapse to a suspected deliberate attack. The candy itself, broken in the hurried response, becomes the first direct clue the Investigators can examine.

Medical and Police Inquiry

The immediate response establishes both the seriousness of Gwen’s condition and the limits of what is known at the scene. John Murphy later reports that the chocolates contained something poisonous, but the hospital laboratory is still analyzing them to determine exactly what it was. Gwen’s stomach has been pumped, and she is in a private room under observation. The poison is therefore confirmed before its precise identity is known; the account does not name a substance.

The police are called and question Mrs Bortz about the package. Her visible role in handing it to Gwen makes her relevant to their inquiry, but the evidence does not say that the police accuse her of sending poisoned candy. Murphy says she takes the questioning personally, as if she believes she is being accused, and he adds that no one has made such an accusation. He also says the chocolates came through the mail and that there was nothing unusual about their delivery. The contrast between the recorded handoff and the reported postal delivery leaves an important distinction: passing a package to Gwen is not the same as having sent it.

Murphy’s Responsibility and the Purpose of the Attack

The later explanation resolves that distinction. In the closing account of the case, Jupiter states that Murphy did send poisoned chocolates to Gwen, intending to make her too ill to swim. The revelation retrospectively changes the meaning of the courtyard scene. The package’s arrival and Mrs Bortz’s handoff had been visible from the start, but neither fact identified the sender; the culprit and the intended effect emerge only with the wider solution.

The poisoning is also placed among Murphy’s other crimes. Jupiter says that Murphy struck Earl, committed a burglary, and attempted to extort money from Fenton Prentice. The chocolates are thus not an isolated accident or an unexplained illness but one act in a series of deliberate offenses. The account gives no further explanation for why Gwen’s swimming mattered to Murphy, and it does not disclose the poison’s exact composition. What it does establish is the central reversal: a seemingly routine gift, opened in full view of the Investigators, was a means by which Murphy tried to keep Gwen from swimming, while the person seen handing it over was not identified as its sender.
