Charles continues to hear rats behind the walls, despite assurances there are none, and his search for answers leads to an insane asylum where his worst fears are realized.

I’m going to assume you’ve already seen episode two, as Charles is still reeling from the shock discovery at the end of that episode, namely that Stephen’s grave is empty. Maybe the locals are correct – and not just overly superstitious – in believing that his cousin is a necromancer (or worse) and killed the child in town.

In between dealing with more violence from the townsfolk, Charles investigates his family’s mental health by visiting a sanatorium and discovering that the same affliction suffered by his forebears, and drove them to madness, is the same condition he is dealing with – an obsessive fear of worms. Elsewhere, a pale girl with a rotten apple advises Tane to tell his father to find ‘the book’.

Verdict: It’s a slow burner, but plenty is delivered in the quality supernatural chiller which is sowing the seeds for some grim discoveries. 7/10
