SILENT WITNESS, ABC1, 8.30pm
WE open with a montage that sets up the backstory of a murdered factory owner so quickly it could be mistaken for a recap of a previous episode. You won’t think that though, because it’s intercut with a cage-fighting match. This seems a puzzling meta- phor for the business world, until you realise it’s just a way of introducing Emilia Fox’s new onscreen partner, Jack (David Caves), who replaces former ‘‘ on again/off again’’ guy Harry (Tom Ward). Featuring nasty unionists, illegitimate children and shadowy escorts, the mystery unfurls like a flower as more and more information is revealed.
