Robert Lindsay joins the cast of Jack Whitehall’s comedy-thriller this week as Barnaby’s dodgy antiques dealer dad Nigel, who discharges himself from hospital and promptly goes on the run.

After learning that his father has a mistress, Barnaby (Jack Whitehall) decides to pay her a visit with Nina (Rosie Perez), during which the Puerto Rican attempts an English accent as the duo pretend to be police detectives called Hall and Oates!

The series is hitting its stride now, combining slick action sequences – such as a chase through London’s Tate Modern – with a fast-moving plot and some deft comedy touches.
