Kevin Whately stars as Detective Inspector Robbie Lewis in four new stories, ably assisted by his partner DS Hathaway, played by Laurence Fox. Together they investigate more murder mysteries against the historic and glorious backdrop of Oxford and its University campus. Episodes include: The Soul Of Genius; Generation Of Vipers; Fearful Symmetry; The Indelible StainThe Soul Of Genius When botanist Liv Nash accidentally digs up the body of the recently buried Murray Hawes, Lewis and Hathaway are set upon a seemingly impossible quest. Murray was a man possessed, fixated upon "solving" an impossible riddle by Lewis Carroll. But could his obsession have been dangerous enough to get him killed? Generation Of VipersLewis and Hathaway are drawn into a world of virtual bullying, but very real murder, when Professor Miranda Thornton is found dead after her dating video is leaked onto a vicious website. Although initially it appears to be a suicide, the deeper they investigate, they realise that Miranda's death is actually the final revenge of an old enemy. Fearful SymmetryWhen babysitter Jessica Lake is discovered dead, Lewis and Hathaway are drawn into diverse new worlds beyond the usual Oxford colleges--squats and swinging suburbia, monkey labs and fetish photography. But which of these new realms led to the murder of Jessica Lake? The Indelible StainWhen controversial American academic, Paul Yelland, is invited to speak at Oxford's Department of Criminology, it stirs up a lot of deep-seated emotions. And when he is found strangled in his room later that night, Lewis and Hathaway have several suspects who fall into the frame--was his murder motivated by politics, ambition, or vengeance?
