Set in 1960s England, the series stars Lorna Watson ( Watson & Oliver), reprising her role as nun, moped rider, wine maker and part-time forensic scientist Sister Boniface. The year is now 1955 and Chief Inspector Sullivan and Mrs Devine seem to be getting rather close, much to the interest of Father Brown and Brenda!

We’re not yet sure if Father Brown himself, actor Mark Williams, will make a guest appearance again. Felix was supposed to be on secondment to the Metropolitan Police but an administrative error lands him in Great Slaughter. A cast of eccentric local characters combined with his boss’s reliance on a nun leave him reeling. Although as Detective Inspector Sam points out, that “Nun” ensures they have the highest clean-up rate in the county. The Doctor Who train just keeps on rolling. Hot on the heels of the news that we will finally be able to see the 60th anniversary specials across three Saturdays from the 25th November - that'll each [...]
