Marcella returned for season three with a new format that featured our titular detective taking on a new identity in a new city to infiltrate the criminal Maguire family in Belfast.
In true dynamic Marcella style, she took the family down one by one – literally
and metaphorically – with a finale that appeared to provide our beleaguered protagonist with a happy ending. She drained their bank account of millions of pounds, kidnapped the sole Maguire heir, took on yet another alias, and hired a private jet to fly her to a far flung country to start afresh.
