Silent Witness: One Of Our Own, BBC One, 9pm

Part one of a two-parter which marks the end of this series of the maddeningly inconsistent but long-running forensic drama. Tonight, a policeman is found beaten and shot in a burnt-out car in Essex. Naturally it's a big case for DCI James Sullivan (Mark Frost), and attention first turns to the drug dealer son of local gangster Dean Fallon (James Farrar). But if his alibi is as strong as it appears, could there be another reason for the murder? When the investigators learn that the dead policeman was having an affair with a married woman, another suspect comes into view: her husband. Concludes tomorrow.

Football Focus: Transfer Deadline Day Special, BBC One, 10.45pm

No, trust me, this is great fun even if you're not a football hipster. Already a fixture in the calendar on BBC Radio Five Live, the Beeb brings the whole January transfer circus to TV and it really can get quite dramatic, with faxes pinging backwards and forwards between clubs and agents, and more zeroes than you can shake Mario Ballotelli's car keys at (that's zeroes as in numbers on transfer prices, by the way, and not a comment on the presenting skills of host Dan Walker or any of his team of pundits). So, Bale to Man U, de Gea to the Bernabeu, and St Mirren hardman Jim Goodwin to the SAS? Watch this space.
