Emer Byrne (Death in Paradise)

Emer Byrne aka Megan Colley (Emily Taaffe) is a villainess from "Erupting in Murder", the Season 6 premiere of BBC's Death in Paradise (airdate January 5, 2017). She was a junior geologist at the Saint Marie Volcano Observatory, working alongside chief volcanologist Stephen Langham, with Stephen acting as a mentor to Emer.
Emer's backstory revealed that she had failed university, and was unable to tell her parents after they had used all their savings to send her to college. Instead, Emer adopted the identity of her friend Megan Colley and used it to join the Saint Marie Volcano Observatory. Sometime prior to the episode's events, however, the observatory's geophysicist Victoria Baker discovered Emer's true identity and used her secret to enlist her in a plot to kill Stephen.
Mayor Joseph Richards had contacted Stephen, offering the team four million dollars in exchange for moving the exclusion zone they'd set up for the volcano on Mount Esmee so he could build a new oceanside hotel. Stephen vehemently refused the offer, leading Victoria to enlist Emer and Daniel Langham (Stephen's brother who was in debt due to having a drug addiction) to kill Stephen and split the four million dollars. Emer assisted Victoria and Daniel in suffocating Stephen to death, pumping CO2 into his bedroom and later putting his body on Mount Esmee to make it appear he had gone out to observe their seismometer overnight and suffered a fatal heart attack.
Over the course of their investigation, DI Humphrey Goodman and Florence Cassell discoverred Emer's true identity and confronted her, with Emer confessing while making the claim that she wouldn't kill Stephen to cover her secret. But ultimamtely, Humphrey uncovered the scheme Emer was involved with, having become suspicious by the fact that a torch wasn't found near Stephen's body, despite him supposed going out to the mountain at night. Humphrey gathered the observatory team together along with Mayor Richards to expose the plot, during which Humphrey correctly deduced that Emer had cared about Stephen and joined the plot under threat from Victoria of exposing her identity theft. As Emer broke down in tears, she was arrested (off-screen) along with the rest of her cohorts and Mayor Richards (who was an accessory after the fact).
