From Doon with death : the first Inspector Wexford novel
(Book)

There is nothing extraordinary about Margaret Parsons, a timid housewife in the quiet town of Kingsmarkham, a woman devoted to her garden, her kitchen, her husband. Except that Margaret Parsons is dead, brutally strangled, her body abandoned in the nearby woods. Who would kill someone with nothing to hide? Inspector Wexford, the formidable chief of police, feels baffled -- until he discovers Margaret's dark secret: a trove of rare books, each volume breathlessly inscribed by a passionate lover identified only as Doon. As Wexford delves deeper into both Mrs. Parsons' past and the wary community circling round her memory like wolves, the case builds with relentless momentum to a surprise finale as clever as it is blindsiding.
