There are some days when being the Garda Sergeant of a small Irish town really tests me. Having to police my family and friends is a necessary evil, but when I'm faced with arresting half the children in the town, and discovering someone close to me among the offenders, well, those days I really wish I'd chosen a different career.

Irate parents are not my only problem unfortunately, as I'm then called to manage a baying mob of strangers, bearing placards and demanding change. I'm all for peaceful protest, but these people were threatening the vulnerable, and I'm just not having that.

So, after a very long week, I just want to go home and put my feet up, when a dramatic, decades-old secret is revealed. It shocks everyone in the family to the core, and it feels like everywhere I turn, where once there was trust and honesty, now there are nothing but lies.

I usually know what to do for the best, but faced with this, I'm unsure. Should I trust my instincts and bend the rules, or should I apply the law to the letter?
