CASTLE

3PM, GREAT! TV ★★★

Fun US whodunnit that has a Moonlighting-style ‘will they, won’t they’ couple at the centre. One is a man-about-town author, the other a tough cop with a tougher secret (The Rookie’s Nathan Fillion and Stana Katic, left). A weekday repeat from the beginning for all eight seasons begins this afternoon.
