Solicitor Benedicta "Ben" O'Keeffe and her boyfriend Police Sergeant Tom Molloy race to Dublin after hearing that some strangers had moved in with Ben's parents. When they arrive, only Ben's parents and their strange lodger remain, but come morning the lodger has left. Not wanting to leave them alone, Ben persuades her parents to come and stay with her in Inishowen.

In Glendara, preparations are underway for Glenfest, Glendara's literary festival. Phyllis Kettle, the local bookshop owner, is especially pleased to have persuaded Gavin Featherstone, the local bestselling recluse writer, to take part.

The festival begins, and an eager crowd awaits Featherstone's appearance on stage. He is unexpectedly engaging, but when he stands to read from his new book, he stumbles and keels over on the platform.

Ben discovers that she holds Featherstone's will at the office, drafted by her predecessor. Soon, she's drawn into a complicated legal wrangle over the man's estate involving his family and the assistant who lived with him.

But nothing can yet be resolved, as a killer cannot inherit from their victim—and Gavin Featherstone's death was a murder.
