Caedmon's Song - Peter Robinson

On a balmy June night, Kirsten, a young university student, strolls home through a silent, moonlit park. Suddenly her tranquil mood is shattered by a swift and brutal act of violence. When she comes to herself she has lost all memory of that bloody night. But then, slowly and painfully, details reveal themselves to Kirsten -- dreams of two figures, one white and one black, hovering over her; wisps of a strange and haunting song; the unfamiliar texture of a rough and deadly hand ... In another part of England, Martha Browne arrives in Whitby, posing as an author doing research for a book. But her research is of a particularly macabre variety. Who is she haunting with such deadly determination? And why?
