Based on the second novel of Val McDermid's Inspector Karen Pirie series, A Darker Domain, season two is set to air in three parts.

The synopsis teases: "After her bittersweet success in series one, Karen has been promoted to Detective Inspector and seemingly given the authority she has long been fighting for.

"Just as she's getting into the swing of her powerful new role, she is assigned an infamous unsolved case that will put her under intense scrutiny; from her boss, from the media, and ultimately, from sinister forces that would rather the past stayed in the past."

The cold case in season two follows the 1984 kidnap of charming heiress to vast oil fortune, Catriona Grant, and her two-year-old son Adam.

They were kidnapped at gunpoint outside a fish and chip shop in Fife, and were never seen again, despite an uncontrollable press storm.

When a man's body is discovered with links to the original kidnap, marking the first piece of evidence in decades, Karen and her team take on one of the biggest challenges of their careers.

"As Karen delves deeper into what happened in the autumn of 1984, political grudges and painful secrets reveal themselves, and it soon becomes clear... the past is far from dead," the synopsis teases.

Karen Pirie season 2 will air on Sunday, July 20, with the first episode premiering at 8pm on ITV1.
