'We know you know. Talk and you're next.'

Bishop Jeremiah Dawodu, pastor of a Nigerian megachurch, has been arrested and charged with the murder of his wife, Folasade, the 'First Lady' of the church. The arrest was public, humiliating and sensational - sending shockwaves through Lagos - but throughout it all, Bishop Dawodu maintains his innocence.

Philip Taiwo, an acclaimed investigative psychologist, is asked by his sister, a member of the church's congregation, to clear the pastor's name. With no actual body, it looks to be a simple case and despite Philip's dislike of organised religion, he agrees to take it on as a favour to his sister. Then the First Lady's body is found in a nearby lake just as Philip's beloved family come under attack from someone warning him off the case, and he realises that nothing to do with this investigation will be straightforward.

Was it murder or suicide? Is someone framing the Bishop or the First Lady?
