Suspects takes a different approach to how crime drama is created and executed. Fay Ripley plays D.I. Martha Bellamy. Witty and warm, Martha fiercely protects her team - and she's exactly the kind of cop you want knocking on your door when your world has been turned upside down. Damien Molony plays D.S. Jack Weston, whose easy charm belies his killer gut instinct. Jack is a man of action - coupled with acute emotional intelligence. Finally, Clare-Hope Ashitey plays D.C. Charlotte (Charlie) Steele, who has a keen eye for detail and whip-smart instincts which help her cut to the heart of any investigation.
