John Davies lists programmes worth catching this week (times pm unless stated).
Pick of the week
The first of a new C4 archaeology series, Secrets of the Dead (Tuesday 9.00) has an interesting story to tell: it's about a recently discovered mass grave that survives from the Battle of Towton (1461), one of the bloodiest clashes in the Wars of the Roses. A team from Bradford University, plus other authorities from Sandhurst, the University of Utah and elsewhere, give their verdict.
FRIDAY June 25
The Index (3.30 R4). Last of five enlightening programmes features Malcolm Bradbury, biographer Richard Holmes and his indexer Douglas Matthew.
SATURDAY June 26
The Muse and the Microphone (8.00 R4). Andrew Motion introduces archive radio recordings of poetry, from John Drinkwater and Hilaire Belloc to the present. More poets follow directly on R3 with Rhymescapes (9.00), which this week deals with "Englishness".
Timewatch: Letting the Genie Out of the Bottle (9.40 BBC2). Last in the current Timewatch run looks back just 30 years, to Denmark's decision to lift all restrictions on pornography.
