Captain Vincent Kronin has been doing day duty from 8am to 6pm. On arriving at the station house, he read over the reports and communications that had accumulated since he went off duty twenty four hours previously. After turning out the platoon, Sergeant Rosen was waiting for him inside the office. Bradley and Warne are two of the patrolmen at the station, but neither have arrived for their patrol today - so Sgt Rosen's suspicions have arisen.
