Follow this hunt for a nefarious serial killer who has slipped under the radar for decades, made only more difficult by pandemic restrictions. Faced with their toughest case yet, the Department Q team must race to find the culprit before the next murder is committed, as it is becoming increasingly clear that the killer is far from finished.

The book is out 27 September 2022.
