DI Tim Williamson

Tim is a police detective who worked with Marcella previously. They have history together: the hints of a frisson and what might have been - if she hadn't met Jason. It's a door that's never quite been closed. In his capacity as detective, Tim doggedly pursues truth and justice but as Jason Backland comes on his radar in a murder investigation, his honest investigative drive is toughened by personal prejudice.
