Jack Lowden, Saskia Reeves and Christopher Chung are set to attend a special screening of the first episode from season four of Apple’s Slow Horses in London.

The trio are due to take part in a Q&A at BFI Southbank on Monday 2nd September. A screening of episode one of the new series will also take place.

The show is based on the novels by Mick Herron and stars Gary Oldman as repulsive but mentally sharp spook Jackson Lamb, who heads up MI5’s department of rejects. In the new series, Lamb’s band of demoted spies face their biggest threat yet when a bomber targets Slough House.

Tickets go on sale on 8th August.
