Timecaster

Chicago, 2064: Talon Avalon is a timecaster – one of a select few peace officers who can operate a TEV, the Tachyon Emission Visualizer, which records events (most specifically, crimes) that have already happened. With crime at an all-time low, Talon has little to do except give lectures to school kids and obsess on his wife's profession as a licensed sex partner. Until one of her clients asks Talon to investigate a possible murder. When Talon uses the TEV to view the crime, the identity of the killer is unmistakable – it's him, Talon Avalon.
