Saturday, 7.30pm, ABC1 Based on a character devised by author GK Chesterton, Father Brown (Mark Williams — Harry Potter, Doctor Who) is a benign parish priest in a bucolic English village who spends a disproportionate amount of time solving crimes rather than tending his flock. Gentle stories with a touch of humour and always a twist, the series is worth watching for the beautiful scenery alone. In this episode, The Wrong Shape, Father Brown is off to a poetry recital by a local writer, Leonard Quinton (Robert Cavanah), who’s subsequently found hanging in the conservatory. It looks like suicide, there’s a note, but our supersleuth is troubled by the fact Leonard was left-handed and the note and the rope’s knot could only be the work of a right-handed person. Who’s to blame? The troubled wife, the Indian gardener, the mistress, the angry solicitor? Therein lies the twist.
