Ep 3. The Eve of St John

In the third episode of Father Brown season 5, titled "The Eve of St John," Father Brown finds himself embroiled in a sinister plot involving a family curse, a stolen diamond, and a murder.

The episode opens with Father Brown and his friend Lady Felicia attending a party at the home of the wealthy and aristocratic St. Claires. The occasion is the eve of St. John, a traditional pagan festival that celebrates the summer solstice. However, the festivities take a sinister turn when Lady Felicia's necklace, a valuable diamond, is stolen. And when one of the guests is found murdered in the woods outside the house, Father Brown sets out to uncover the truth behind the theft and the killing.

As Father Brown delves deeper into the mystery, he discovers that the St. Claires have a long and bloody history that dates back to the time of the infamous Witchfinder General.

As Father Brown uncovers the complicated web of lies, secrets, and deceit that lies behind the seemingly innocent party, he must also confront his own inner demons. He is haunted by memories of his past, and he worries that his own sins may have contributed to the tragic events that are unfolding around him.

In the end, Father Brown uses his powers of deduction and his unshakeable faith to solve the case and bring the killer to justice.
