McDonald & Dodds series 4 episode 1 cast: The Rule of 3 stars singer Pixie Lott in rare acting role

There's a Line of Duty star, Australian hunk, and a film legend from the 80s too!

McDonald & Dodds is back with the long-awaited series 4, and the cast of episode 1 – The Rule of 3 – is full of famous faces.

Fans haven’t seen DCI McDonald and DS Dodds since series 3 ended in 2022 – and it’s felt like a long wait for more episodes. But the wait is over, and Jason Watkins and Tala Gouveia are back for three new feature-length episodes.

As series 4 kicks off, the detectives investigate when a woman is found dead in a rented flat. The killer has removed all clues to the victim’s identity, but DNA reveals that she’s a missing person who vanished on her way home from school more than 35 years ago.

Can McDonald and Dodds navigate the tightly-wound social circles of Bath’s elite to find the truth? The investigation begins with her only living relative, her twin brother – now a wealthy financier living the dream in one of Bath’s most prestigious addresses.

Despite his obvious grief and trauma, it becomes clear Mark may be concealing a dark and long-buried secret of his own… Here’s everything you need to know about the cast of the returning drama.
