Trivia / Sister Boniface Mysteries

• Fake Nationality: Anglo-Nigerian actor Jerry Iwu plays Barbadian policeman Felix Livingstone. It can come as a surprise to hear him speaking out of character, as he grew up in Ireland and his natural accent is part-Nigerian, part-Irish.
• Recast as a Regular: Ami Metcalf plays the main role of WPC Peggy Button, having previously guest starred as nurse Alice Bonham in Father Brown.
