Alongside those working closest to the case, Hill examines how Irish dance champion Adrian Murphy fell victim to the fatal intentions of Diana Cristea and her boyfriend Joel Osei. Cristea and Osei targeted victims on the gay dating site Grindr, plotting to drug them with scopolamine and strip their homes of valuables. Adrian Murphy died from a lethal dose of the drug at a Battersea flat on 4th June 2019, while two days later a second man was also drugged and robbed by the couple but survived. The discovery of Adrian’s body sparked an investigation that revealed the couple’s deadly use of scopolamine, which earned its sinister ‘Devil’s Breath’ nickname.
