Edinburgh 1810: Charles Murray of Letho, a young gentleman of means, is in much demand: a rich widow, an old friend, and new military acquaintances all need his help. But when Henry Dundas, Viscount Melville, sends him an invitation, vanity and curiosity force him to accept - and straightaway he has to deal with murder. Why did a cowardly surgeon kill a drunken engraver? And what would the consequences be, in the rainy mists of autumn? In the end Murray's answers to his problems will lead to a decision that will change his life. Fellowship with Demons is the fifth in the Murray of Letho...

It's a long walk home to Ulster from Glasgow University - and even longer when the journey is interrupted by murder. Murray of Letho is staying with an old friend in the fishing village by Loch Ryan where the unpopular Newell meets his death. Missing his daughter, resenting his mourning and distracted by an abundance of charming female company, Murray struggles to find the murderer amongst a host of suspects, in a village where every second inhabitant has motive, means, and a fine knowledge of poison.

The dreadful day is approaching for the Napiers in Ballater: Hippolyta Napier's mother is coming to stay. But Mrs. Fettes is not just in Aberdeenshire to visit her youngest daughter: she has other reasons, and one will draw the whole family in, with deadly results.

The distant Scottish spa town of Ballater seems a world away from the stylish and familiar streets of Georgian Edinburgh, but recently married Hippolyta Napier is making a new life amidst its dark woods and pure, flowing waters. But suspicion, intrigue and death await both inside and outside her new home, and the forces of nature take few prisoners.

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.

The sun is shining, Ballater is full of wealthy visitors, and Mrs. Kynoch's school for young ladies is flourishing - until one pupil, the daughter of a slave-owner, vanishes. Has she eloped with a rich man, or is something more sinister afoot? Hippolyta Napier needs to know, before a vulnerable local man is accused of something he could not have done.

'Uncle!' The man lay with his head propped against the standing stone - what was left of his head. Hippolyta swallowed hard. 'I'm a doctor's wife,' she told herself. 'I can manage.' No one can think why this man has been murdered, nor why passing farmer has also been attacked. But as Hippolyta Napier does her best to assist the sheriff's man in damp, autumnal Ballater, they gradually unfold a web of violence, past tragedy and present crisis, threatening anyone who comes near it. A Lochgorm Lament is the fifth in the Ballater Murder series, set in 1830s Scotland.
