Three people are murdered on separate Tuesday evenings at precisely 11.05. Random clues point to random suspects, but too many questions remain unanswered. Why 11.05pm for each killing? Is there any connection between these deaths and a rape that occurred at Queen's university twelve years before? What is the connection between the killings and Sergeant Stewart's mystery informant? Who is the violent stalker who twice nearly kills Detective Allen? What is his connection, if any, to the murders? When one of his team is kidnapped, Inspector Sheehan has literally only minutes to make sense of these questions if he is to save his colleague's life.
