It's been six weeks of shocks, plot twists and sassy-one lines from our favourite Calderdale copper, Sgt Catherine Cawood.

Happy Valley series two has come to an end — and I've loved every minute.

There may be some delay before series three happens ( but it should happen ), so while we're waiting, here's some of my personal highlights from Happy Valley series two.

My series two highlights:

Catherine vs Tommy

He may be locked up at the other end of the country, but that didn't stop Catherine obsessing and seething over Tommy Lee Royce this series. She turned up at his mother's funeral to taunt him, silently, from the back of the crematorium, and almost had a breakdown over the birthday present to Ryan from 'Dad'.

Down in Graves End, Tommy spent his days becoming ever more bitter about Sgt Cawood — for locking him up, keeping him away from Ryan and, bizarrely, for killing his mother (even though she didn't). The pair only had brief contact this series but they were never far from each other's thoughts — it wasn't healthy, but it made great TV.

Ann Gallagher returned

After the trauma she endured in series one, Ann bounced back in series two to return as a PCSO and was taken under Catherine's wing. And she's definitely a detective in the making, making clever deductions and storing useful information left right and centre. Without her impressive memory, Catherine might not have twigged about John Wadsworth.

Frances Drummond was queen of creepy

A hat-tip to Shirley Henderson, who made Frances Drummond the creepiest, quietest, most unnerving woman ever. She spent six weeks hiding around corners, squeaking her lines and grooming Ryan, before being rumbled by CCTV and Clare's keen eye.

I was glad when the petrol-bomb plot didn't come off — while some may have been disappointed, I felt it was more loyal to her character to cut out some mad attack on the Cawoods. She's a god-fearing woman who believed she could reform Tommy Lee Royce, not a violent criminal.

The downfall of John Wadsworth

Kevin Doyle was fantastic as John Wadsworth, the bumbling murderer who thought he'd carried out the perfect cover-up before his world crumbled around him. His bitter side in scenes with wife Amanda made you want to slap him, and as the police got ever closer to figuring out he was Vicky Fleming's killer I was cheering them on. Series two saw John get paler, sweatier and more panicked as the weeks went by — until he met his sad end. Some fantastic black humour there too, with John instructing Catherine on the finer points of suicide negotiation.
