Blood Cull - Doug Brown, #2

A series of ritualistic killings. A retired detective inspector desperate to save his wife. A horrifying secret. Detective Inspector Doug Brown has retired to Scotland, but when his wife falls ill, there is no choice but to take on a private contract offered by an old acquaintance. Soon he finds himself on a dark path, tracking down a ritualist killer of affluent men, who has so far eluded the police.
But as the merciless killings continue, Doug is unknowingly getting closer to unveiling a sickening conspiracy. Blood Cull is a slow burn page-turner from USA Today best-selling authors, Jay Tinsiano and Jay Newton, that will keep you on edge until the end.
