The Labyrinth of the Minotaur (S05E02)

An intruder enters Lady Felicia's bedroom, snapping on the light to reveal her niece Bunty. She's gone on the run after being photographed with a married man - can she stay with her favourite aunt? Felicia asks Father Brown and Mrs. McCarthy to look after Bunty while she attends business in London. They visit Davina, Lady Malmort to see how wayward girl Ruby is faring as the new maid. Davina's son Bobby is thrilled to see Bunty, insisting she stay for dinner. That night Bunty finds Ruby in her room trying on a stole, which Bunty gives to her. (iTunes)
