Episode 110
The United Britain beauty contest comes to Slaughter Abbey, and one of the three favourites is found dead in the swimming pool. 

It’s the 1960s and police forensics are rudimentary. Luckily the residents of Great Slaughter have a secret weapon. Sister Boniface. If there’s evidence to be found, Boniface will find it, with a little help from dashing DI Sam Gillespie and buttoned-up Bermudan DS Felix Livingstone.
