Professor T ITV, 9pm

Ben Miller (below) returns as Jasper Tempest, the University of Cambridge criminology professor whose interest in lawbreaking isn’t purely academic – he also helps the police with their investigations. In the opening episode, the CID team reluctantly calls on his expertise when it emerges that a house fire that left a student in a coma was started deliberately – and the victim was drugged in advance. ★★★★★
