CASTLE, Channel 7, 9.45pm
AUSSIE Brett Tucker (pictured) guest stars as a Scotland Yard detective who teams with Castle to help solve the murder of a friend’s daughter. The former Neighbours star puts on a British accent and takes off his clothes to play Colin Hunt. And Beckett is closer to admitting her feelings for Castle. There are worrying shades of Moonlighting. When Moonlighting’s Bruce Willis and Cybil Shepherd hooked up, the chemistry died, as did the show.
