DS McAllister is surprised to run into her former lover and informant Jamie Ross in a bar, when he returns to Sun Hill after the man who wanted him dead dies of a heart attack. Ross is in a new line of work: organising adventure holidays - but he still has plenty of inside knowledge, and when he and McAllister resume their relationship, he reveals the man responsible for a hit-and-run on a drug dealer and a schoolgirl. To McAllister's horror, she realises that Ross has used her, as he is deeply in debt to Brett Sadler who ordered the drug dealer killed. DI Cullen convinces Ross to help them catch Sadler, but Ross is shot and killed by a sniper. (thetvdb.com)
