While retracing the Maitlands’ recent family vacation, Holly pursues a possible connection to an eerily similar case and gains valuable insight from local former detective Katcavage.

If there was any doubt last week, it’s clear now – this is Holly Gibney’s show, and Cynthia Erivo is superb as the private detective with the knack of being able to retrace crime scenes. She’s relentless, gaining a squirt in the eyes with pepper spray for pursuing the receptionist at the home where Maitland’s father resides. But it’s worth the discomfort, as she’s able to fill in some essential blanks in the story.

While Holly is busy forming connections with the murder of the Williams sisters, Detective Anderson (the always excellent Ben Mendelsohn) is pursuing his own line of enquires with the Maitland case, picking away at the contradictory evidence and also getting a break when an image of the mysterious hooded stranger is drawn by a young witness.

There’s much talk of ancient evil and the role it plays in different religions. The deeper she goes, the more that Holly picks up wider connections and a trail of innocent victims, whose families are fed upon by the grief-eating entity that hangs around to feast on the misery of those left behind. And just what is infected detective Hoskins planning to do with all that equipment he’s bought from the hardware depot? I think we know the answer.

Verdict: While we’re no closer to resolving the mystery, its scope and scale are becoming clearer, with the suggestion that we’re in the presence of something ancient and truly evil. Fascinating, and in no hurry to rush matters, it’s an engaging hour. 8/10
