Passion investigates True North series

Passion Distribution has struck a deal with Leeds-based indie True North Productions to distribute its crime documentary series Killer Couples.

The 4 x 60-minute series investigates the relationship between some of the most notorious partners in crime, such as Myra Hindley and Ian Brady.

It features best-selling crime novelist Mark Billingham getting inside the mind of a different killer couple in each episode. Passion has picked up the rights to distribute the series worldwide.

The series was produced and directed by Luke Mclaughlin, whose film The One That Got Away is one of Crime and Investigation Network's highest-rated shows.
