When a woman is found dead, laid out in the shape of a crucifix on Jesus Green, Will and Geordie discover the ring on her finger proves she was married to God – and a former nun at an oppressive convent. And as Geordie and Larry both agree – there’s nothing scarier than a nun…

At the convent they meet steely Sister Grace, who rules over her flock with an iron fist. But even more sinister is the picture that starts to emerge as they match the nuns to a series of unsolved missing persons cases from the last five years. This is anything but a place of sanctuary. But can Geordie and Will save its victims before it’s too late?

All the while, Will tries to deal with his own feelings of guilt – what he needs is a kindred spirit, able to salve his aching soul. What’s certain is this won’t be a birthday he’s likely to forget any time soon…

When Leonard’s dad, Russell, arrives in Grantchester, it’s clear there’s no love lost between father and son. But in order to heal the wounds of the past, will these two men be able to find common ground?
