TWO BRUTAL SLAYINGS AT A BARN DANCE.

Detective Ava Merry has a knack for spotting trouble, even when she's off the clock.

She goes to a forties-themed dance at Northfields Farm on Valentine’s Day and discovers a young couple, Nick and Samantha, murdered.

Nick is found dead in a vintage ambulance. Sam is found stabbed multiple times in the glamping tent where they were staying. A man collides with Merry as he flees the scene.

Who is he and is he really innocent?

DI Jim Neal joins the investigation. But everywhere Merry and Neal turn, they are confronted by lies. Then another frenzied murder ups the stakes still further.

CAN MERRY AND NEAL EXPOSE THE KILLER WHEN NO ONE IS WHO THEY SEEM?
