Scotland at the beginning of the nineteenth century. Scoggie Castle is cold and grim, but a refuge to the disinherited Charles Murray. Then a series of mysterious deaths shakes family and servants alike, and splits the local village in two. Murray is thrown once more into the midst of murder, but who has the answer in this dark rural landscape - the pig-lovers or the pig-haters? Knowledge of Sins Past is the second in the Murray of Letho series, set in Georgian Scotland.

Charles Murray is in Edinburgh when tragedy strikes him. The deaths of a lawyer and a servant not only draw him down to the homes of the capital's grim underclass, but also make him reconsider his elegant society friends. Yet is everything quite as it seems? Who kills - and who gives the orders? Service of the Heir is the third in the Murray of Letho series, set in Georgian Scotland.
