DCI Barnaby and DS Jones investigate when organiser Toby Winning is found dead on the day of the Little Crosby Folk Festival, drowned in a bowl of eggs and live eels.

Did someone want to kill Toby for threatening to take the festival away from Midsomer – or is the true motive something hidden for 20 years?
