In Down Cemetery Road, all paths lead to Dinah and, in this case, to a small island in Scotland that was literally wiped off the map. In a spectacular, tense, and unpredictable episode — if the trailer hadn’t spoiled everything a month ago — I would have been genuinely terrified for Zoë. And even knowing she would escape at least this one, I believed every second that she might join Joe (in other words, die).

As we already knew, Zoë was following Amos, and he was more than aware of it. On the train, he prepares to eliminate her, and it’s impossible not to praise Fehinti Balogun’s performance, which channels Javier Bardem in No Country for Old Men: silent, methodical, absolutely terrifying. He approaches Zoë and, without exchanging a single word, the two deliver a masterclass in writing, tension, and acting.

The journey to Scotland feels even longer than necessary. Zoë, always crafty, tries to shake Amos by joining an American tourist couple, then hides in a cabin, creates distractions — she basically becomes a mosquito impossible to squash. She gives him so much trouble that he initially backs off — but not before finding an excuse to stop the trip in a small town and resume his pursuit of Downey. What follows is one of the darkest sequences in the entire series: Amos, now free from Zoë, kidnaps and murders the American couple, calls the police, describing Zoë as “a face of pure evil,” and leaves behind the Polaroid where she’s smiling with the victims. It’s brutal, dry, and confirms what we already knew: he is a patient, intelligent, implacable predator.

In London, C confronts Malik for lying (well, actually for being wrong) about having eliminated Amos, who, ironically, has been more efficient at erasing the traces of the chemical weapon crime than the actual employee. Under pressure from the Home Office, C gives Malik one last order: whether it’s Downey or Amos, whoever survives the confrontation, Malik must kill the last man standing. If he doesn’t, he’ll be eliminated himself.

Meanwhile, Sarah and Downey are camped out in the middle of nowhere, but he disappears during the night, leaving Sarah wandering alone through the town. The truth is that he abandons her to protect her, but Sarah doesn’t quite get the message. In a shop, she overhears comments about an abandoned old military base and rushes there, convinced she’s deciphered another piece of the puzzle and will find Downey at last.

In a direct nod to The Silence of the Lambs, we follow a sequence that seems poised to lead to Dinah — but no. Instead, Sarah runs straight into Zoë. The improbability is forgivable because the chemistry between Emma Thompson and Ruth Wilson is undeniable; it was more than time to bring them together. Zoë asks Sarah to investigate the place further, which clearly matters since both reached it through completely different paths. The detective observes two suspicious fishermen — whom we know are responsible for delivering supplies to Dinah’s mysterious island — while Sarah, at the local pub, notices that an old map shows an archipelago with six islands, while the current map shows only five. Bingo: it can only be where Downey is heading and where Dinah is being held.

Before they can figure out how to get there, Sarah hears that Zoë is being sought as the prime suspect in the murder of the American couple — a piece of news that shakes her, since she knows Zoë couldn’t be chasing someone and killing a random couple at the same time. It only reinforces that they have little time and need to leave the town immediately. They steal a boat, not realizing that it’s not only Downey’s destination — it’s also Amos’s and Malik’s. And, to make everything worse, Downey’s medication has run out.

I can’t wait to see how all these threads collide — and who, in fact, will survive the showdown on this island, erased from the map.
