All the Colours of Darkness: DCI Banks 18

Peter Robinson's eighteenth outing with the brooding, complex DCI Banks plunges into a labyrinth of secrets and shadows. When a retired detective is found dead under suspicious circumstances, Banks must navigate political intrigue, old rivalries, and dangerous truths that some would prefer stayed buried. Robinson masterfully weaves psychological depth with procedural precision, creating a crime novel that's as much about the darkness within us as the mysteries we solve. Perfect for fans of Ian Rankin and anyone who loves their crime fiction layered, atmospheric, and utterly absorbing.
