Summary In his new role as Chief of Police, Bill Jacobs requests a meeting with Da Vinci to discuss his concept of a red light district. Da Vinci is surprised by the request. With continuing investigations, Kosmo and Leary speak to Roy Cardinale's friend, John Dunne. After seeing John speak to the detectives, Constable Dino Rosario has his own chat with John. After checking out some information provided by John, Kosmo and Leary believe that something in his story concerning Roy's whereabouts the evening of his death isn't sitting right. McNab informs the Mayor that his car was indeed involved in a hit and run death. The Mayor seems more interested in retrieving his cell phone from the car, reported stolen that night, than he is about the death. As McNab checks out two of the numbers from that cell phone's records from that evening, he uncovers some unusual information concerning the Mayor's car's whereabouts that evening. Brian manages to have Councillor Pierce's car pulled over, but no knife is found in his possession. Perturbed that his frame on Pierce didn't yet work, Brian plots with Marla to watch over Sue, who was supposed to plant the knife in the car. Brian also uses another tact averting himself from Rick's death by speaking to Detective Joe Finn in Internal about the investigation. And while Shannon is off on personal leave, Williams continues the investigation into the purported self-inflicted shooting death of Michael Zang. In a new investigation, Da Vinci and Lou attend to the death of man who looks to have fallen from a rooftop. They determine the probable cause of the fall when they see some wiring on the roof. They however learn that there is more than meets the eye when they speak to the deceased's neighbors. On personal fronts, Kosmo thinks about buying a house. And Shannon learns that his building has a new no pet policy, meaning he will have to move or get rid of Lucky.
