In season three, Harry and Fergus are hired to prove the lead singer of Ireland's hottest boy band didn't kill himself, find out who decapitated a woman in a busy restaurant, discover who murdered a despotic director on the set of Ireland's leading daytime soap opera, work out how a mystery writer managed to shoot himself in a locked panic room without a gun, and more.

Meanwhile, with the agency still as busy as ever, Harry and Fergus have to find a way to balance work and life as Fergus plans to contest Paula's custody claim to his sister.

Season Two follows former literature professor, Harry Wild, who has found an unusual pastime in retirement: solving crimes along with her young partner in PI work, Fergus Reid. Together the wise-cracking pair investigate cases ranging from missing persons to murders, much to the annoyance of Harry's son, Charlie, who's a detective in the Dublin Garda. When Fergus's mother suddenly turns up, years after abandoning her family, they have a deeply personal mystery to solve: What are her intentions? And can he trust her?

Harriet "Harry" Wild, is a recently retired English professor who finds herself at one of life's crossroads. Jolted from a mugging, she reluctantly agrees to recover in the home of her son, Charlie, a senior police detective. Harry starts to interfere in a particularly baffling murder case Charlie is investigating when she notices the murder shares striking similarities to an obscure Elizabethan play. When her path crosses that of her mugger, Fergus Reid, Harry sees great potential in the troubled teen and, instead of turning him in, enlists him as her sidekick. Following her successful, albeit ill-advised, involvement in the case, Harry discovers a new lust for life as she and Fergus find new mysteries to solve.
