When McDonald checks the report from toxicology, she finds that the victim, 26-year-old Rose Boleyn, had potassium chloride in her bloodstream, hinting towards criminal negligence - or foul play.
You can watch the exclusive clip from Sunday's brand-new episode of McDonald & Dodds here.
The official synopsis for Sunday's new episode, which will air on ITV and is titled The War of Rose, states: "When lifestyle influencer Rose Boleyn checks into Bath’s exclusive Ford & Flynn clinic for a nose job, the worst she is expecting is some backlash from her followers.
"But when the routine procedure goes horribly wrong and Rose dies on the operating table, the clinic’s bickering, soon to be divorced owners Al and Mariel are thrust into the spotlight. In a case of social media vs reality, McDonald and Dodds must separate the fact from the fiction. Was Rose’s life really as glamorous as it looked? Or was it all an illusion?"
The episode features guest stars including Sarah Parish and Rhashan Stone, while the victim is played by Rosie Day. Previous outings this season have had similarly starry casts, with guest appearances so far from Alan Davies, Sîan Phillips, Paul McGann and Louise Jameson, amongst others.
