The murder of former schoolteacher Arthur Leggott in his own home brings Barnaby and Scott to Badger's Drift to investigate. The detectives soon discover that Joan Alder, the late composer of Midsomer Rhapsody, may be a key figure in this case. Could the killer be on the trail of an undiscovered musical manuscript? As the detectives investigate, they discover that there are plenty of wounds left by Joan's death many years earlier. Was her husband, Michael Maybury, responsible? What was the fate of John Farrow, the composer's lover? And what will happen when Joan's long-lost daughter makes an appearance?
