Here’s the trailer for the ninth and final series of Inside No 9.

It was confirmed earlier this week that the show will start on BBC Two and BBC iPlayer at 9pm on May 8. 

The final series commences with another milestone as the first episode, Boo To A Goose, is Steve Pemberton and Reece Shearsmith’s 50^th film. 

The BBC says: ‘From the elegance of an Edwardian country house to the grim reality of the last train home, from nosy neighbours to grave robbers, from illicit visits to the toilet to a ticking clock in a sinister escape room, this ninth collection is sure to send the series off with a bang. 

‘A deadly mixture of classical music, dubious morals and murders at midnight, Shearsmith and Pemberton present six more films to delight and disturb their many fans around the world as they open the door marked No.9 for the final time. ‘ 

Boo To A Goose features guest stars  Siobhan Finneran, Mark Bonnard Susan Wokoma, Joel Fry,  Philippa Dunne, Charlie Cooper and Matthew Kelly.

It revolves around late-night passengers who get stuck in a tunnel when their train breaks down  a but tempers start to fray when a nurse gets her purse stolen

Other guests across the final six-episode series include Dorothy Atkinson, Katherine Kelly, Eddie Marsan, Vinette Robinson, Hayley Squires and Adrian Scarborough, who previously worked with Pemberton and Shearsmith on Psychoville, playing twisted children’s entertainer Mr Jolly.
