Why it matters

Honey, venom therapy and an historic estate give the episode a coherent world in which commerce and belief feed each other.

Ambrose Deddington credits Apley Gold honey and bee-venom treatment with helping him survive serious illness. When thieves target the estate's historic hives and injure him, the value of the bees—and the claims made about their products—comes under police scrutiny.

Local doctor Serena Lowe is subsequently killed using the very insects around which Apley's reputation has been built. Barnaby and Winter examine the household, neighbouring businesses and a previous event that changed several of the relationships now surrounding the estate.

Who was the killer in The Sting of Death? (spoiler)

The present crimes are a reckoning for an earlier event, and the celebrated products of Apley Court become both the murderer's language and the route to the truth.

Who was the killer in The Sting of Death? (spoiler)

Noah Moon (Noah Lyster)

Noah killed Dr Serena Lowe with a deliberately provoked bee attack after confirming that she had helped conceal Ambrose Deddington's false cancer story. He later injected Cal Ingalls with stolen bee venom and staged the body, then tried to kill Ambrose in revenge for the treatment claims that had led his mother to refuse conventional care.

Verified motive

Noah sought revenge for his mother Marnie, who refused conventional treatment and died after believing Ambrose's fraudulent cancer-cure story. He targeted everyone he believed had enabled the deception—confirming Serena's knowledge before killing her, killing Cal as part of the colluding circle and reserving Ambrose for last—while also attacking the hives he felt had failed his mother.
