When two attendees go missing from a folk music festival at a remote Gothic mansion, Inspector Felse arrives to solve the mystery—and protect his son. Singers and musicians are gathered for a weekend course in folk music at the impressive neo-Gothic country mansion Follymead. Most come only to sing or to listen, but one or two have nonmusical scores to settle. When brilliantly talented Liri Palmer sings “Black, black, black is the colour of my true-love’s heart,” she clearly has a message for someone in the audience. And as passions run high, there is murder brewing at Follymead. Among the music students are Dominic Felse and his girlfriend, Theodosia. When not one, but two, members of the group go missing from the hall, Dominic calls upon his father, Detective Inspector George Felse, to help him solve this most perplexing mystery.   Black Is the Colour of My True Love’s Heart is the 6th book in the Felse Investigations, but you may enjoy reading the series in any order.
