Willoughby needed other pictures on the wall like in the best crime movies (The Usual Suspects?) but the cupboard was bare. The team briefing with his detectives dishing out orders was what he craved, the very adrenaline of the job, but there was nothing to go on.

Could the assailant have intended to keep his identity hidden, perhaps on a murder mission himself?
