In MI5 a scandal is brewing and there are bad actors everywhere. A key member of a Downing Street think-tank has disappeared without a trace. Claude Whelan, one-time First Desk of MI5's Regent's Park, is tasked with tracking her down. But the trail leads straight back to Regent's Park HQ itself, with its chief, Diana Taverner, as prime suspect. Meanwhile her Russian counterpart has unexpectedly shown up in London but has slipped under MI5's radar.

Broadcaster, writer, philanthroper and one of the first public figures to suggest high-visibility clothing for people manning temporary car parks, the public Alan Partridge is a cherished institution. But what of the unseen Alan? For the first time, this famously private man welcomes us into his home and audibly deshrouds himself for a fascinating series of podcasts.

He’s the Man With No Name and the owner of No Alibis, a mystery bookshop in Belfast. But when a detective agency next door goes bust, the agency’s clients start calling into his shop asking him to solve their cases. It’s not as if there’s any danger involved. It’s an easy way to sell books to his gullible customers and Alison, the beautiful girl in the jewellery shop across the road, will surely be impressed. Except she’s not – because she can see the bigger picture.

Slough House is Jackson Lamb’s kingdom; a dumping ground for members of the intelligence service who’ve screwed up: left a secret file on a train, blown surveillance, or become drunkenly unreliable. They’re the service’s poor relations – the slow horses – and bitterest among them is River Cartwright, whose days are spent transcribing mobile phone conversations.

Twenty years retired, David Cartwright can still spot when the stoats are on his trail. And he's not as defenceless as they might think. Jackson Lamb worked with Cartwright back in the day. He knows better than most that this is no vulnerable old man. 'The old bastard' has raised his grandson with a head full of guts and glory. But far from joining Spook Street, River Cartwright is consigned to Lamb's team of no-hopers at Slough House.

The 'Old Bastard' raised his grandson to be a hero, not a slow horse. Now, far from joining the myths and legends of Spook Street, River Cartwright is part of Jackson Lamb's team of pen-pushing no-hopers at Slough House. Which doesn't mean he won't ditch everything and go rogue when his grandfather comes under threat. Lamb worked with Cartwright back in the day, and knows better than most that this is no innocent old man.
