Something in the Cup

31. Bellwick dropout who left Dr. Osei's marine biology program abruptly. She was Callum Vries's fixation during his weeks at Undertow. She turned him down gently on September 5th — four days before his death. She was alone in the shop when Callum received his last drink on September 10th. As a former marine biology student, she had coursework in pharmacology and toxicology, including cardiac glycosides. She has told investigators she simply closed up and went home. No one can contradict that — or confirm it.

45. Isla's volatile on-again partner. Multiple witnesses at The Brine heard him express contempt for Callum in the week before the death. A failed academic who now authenticates rare books, Simon has access to Greystone's antiquarian collection, which includes historical volumes on pharmacology and plant compounds. He was present at The Brine on September 7th but has no documented whereabouts for September 10th. His drinking, his jealousy, and his proximity to Isla make him the case's most obvious suspect — which is precisely the problem.

22. Worked the morning shift at Undertow and served Callum his cortado on September 10th — though he went off-shift at 4 PM, before closing. Elliot's Moleskine notebooks document Callum's behavior in detail. His September 3rd entry explicitly notes that Callum 'took it hard' after Isla's rejection. A Bellwick senior in creative writing, Elliot has access to the university's science buildings, including labs where digoxin compounds are used in cardiac research. He found Callum's fixation on Isla alternately pitiable and irritating — his notebooks make no secret of it.

Adrien's ex-partner, romantic and culinary. Remi met Callum twice and was the only person to flag his behavior to police — specifically noting he seemed 'agitated and unusual' the evening before his death. What Remi did not initially mention: he had developed his own feelings for Isla Ferreira after meeting her at a harbor walk event, and had been quietly competing with Callum for her attention. As a professional chef with deep knowledge of food chemistry and flavor masking, Remi would know how to introduce a compound into a beverage without detection. His motive, like Simon's, is jealousy — but Remi's was more recent and, until now, undisclosed.

52. Retired commercial fisherman who runs The Brine with quiet authority. Dean heard Simon's contemptuous remarks about Callum on September 7th and has relayed them to investigators. What investigators noted later: Dean himself had a brief and bitter falling-out with Callum after Callum reported what he believed was illegal discharge from a fishing vessel behind the marina — information Callum gathered for his Bellwick environmental fellowship research. The complaint went nowhere, but Dean lost a customer over it and holds grudges like ballast. He is, however, without the specific technical knowledge required to administer digoxin undetected.
