Tim’s a forensics expert, not only is he a very detailed and brilliant practitioner but he is meticulous and professional. "Often these guys can solve the case themselves and I think because they have the ability to do that, sometimes there’s friction between other departments, particularly with DCI Roz Huntley (Thandie Newton)," says Jason.

"There is a moral call to be made as well as a procedural one and I think if you’re, like Tim, forensically minded and meticulous then it’s hard to square that."

Georgia Trotman, played by Jessica Raine (series 2)
