Dark Origin — Katherine Pathak

Is evil in the blood? When DS Andy Calder busts a small-time pornography operation in south Glasgow, he suspects they've only touched the tip of the iceberg. With the Serious Crime Division desperately understaffed, DCI Dani Bevan brings in a fresh member of the team. The new recruit arrives just in time. A man is found murdered in an outhouse used to produce illicit material and the grisly body-count slowly starts to rise. The 9th instalment of the DCI Dani Bevan detective series follows two complex and distinct cases, each of which call on the team to question the origins of evil itself.
