In the concluding double-bill of the bleak, bloody and brilliant French crime drama, Captain Laure Berthaud and her team are closing in on Ronaldo Fuentes; but will Vincent Brémont and his Crime Squad help or hinder the CID’s progress?

Meanwhile, defence lawyer Josephine Karlsson makes a painful decision to help her colleague Pierre Clément and Judge Roban makes a surprising discovery in the boiler room of Mayor Courcelles’ offices.

The final episodes of Spiral’s third series air at 9pm on Saturday 7th May on BBC Four. In the meantime, here are ten teasing lines of dialogue from the episode…

» ‘I’ll wind Dylan up like a coiled spring. He’ll be so full of hatred that he’ll pass off your shyster as a complete bastard. Rape or no rape, Clément will never recover. It will ruin him.’

» ‘Do your employees know that they are being spied on in the toilets?’

» ‘Your wisdom is of credit to you. Make better use of it in the future.’

» ‘I’ve spent thirty years fighting for justice to mean something; I sacrificed the life I could have had with your mother for my job. So I refuse to betray my beliefs now to pass on the baton to an idiot like you.’

» ‘You work to fill the void, Laure. Look at yourself: you’re scared of living.’

» ‘You don’t care about Pierre – you took on this case to piss me off!’

» ‘Maradona, Maradona!’

» ‘I’ve been pursuing Ronaldo for weeks; he haunts my life and my dreams. You wouldn’t understand.’

» ‘Send Brémont out for sweets. I’ll make the Albanian git talk.’

» ‘If we fuck this up, no one will be in a party mood.’
