In Three's A Crowd, we are introduced to Detective Sergeant Patrick Shea, a rising young star at the Hampden Station Criminal Investigation Department, and someone whose career is being fast tracked by the Metropolitan Police in London. With his eye on an appointment to a Murder Investigation Team with New Scotland Yard, Shea is doing everything by the book. Unfortunately, Patrick's love life is a bit of a mess and gets messier when he learns that his former lover, Annie Jameson, has been assaulted on someone else's patch. Will his involvement in the under-the-radar investigation of the attack on his ex-girlfriend put his career in jeopardy and possibly her life as well?
