The hunt leads them to Ladywell Playtower in Southeast London, the home to a religious commune lead by the enigmatic Aaron Cronin. Archer and Quinn suspect Cronin's involvement but his alibis are watertight, and the truth seemingly buried. If Archer is to find the killer, she must first battle her way through religious fanatics, London gangsters - and her own demons . . .
