The story revolves around the comings and goings at No. 44 Scotland Street, a fictitious building in a real street in Edinburgh. Immediately recognisable are the Edinburgh chartered surveyor, stalwart of the Conservative Association, who dreams of membership of Scotland's most exclusive golf club. We have the pushy Stockbridge mother, and her prodigiously talented five-year-old son, who is making good progress with the saxophone and with his Italian.

Isabel Dalhousie thinks often of friends, sometimes of lovers, and on occasion of chocolate. As an Edinburgh philosopher, she is certain of where she stands. She can review a book called In Praise of Sin with panache and conviction, but real life is...well, perhaps a bit more challenging....

Detective Ulf Varg from the Department of Sensitive Crimes is often called upon to investigate unusual matters. But rarely is he asked to conduct an inquiry on behalf of his own family. Is such a thing ethical? Adding to Ulf's moral discomfort is the fact that he does not exactly see eye to eye with his younger brother Bjorn - a leading player in one of Sweden's right-wing parties, the Moderate Extremists. Still, family is family, so Ulf finds himself working to uncover the mole leaking secrets to a rival party, the Extreme Moderates. 

For years, rumors of the "Marsh Girl" have haunted Barkley Cove, a quiet town on the North Carolina coast. So in late 1969, when handsome Chase Andrews is found dead, the locals immediately suspect Kya Clark, the so-called Marsh Girl. But Kya is not what they say. Sensitive and intelligent, she has survived for years alone in the marsh that she calls home, finding friends in the gulls and lessons in the sand.

'And in Edinburgh of all places. I mean, you never think of that sort of thing happening in Edinburgh, do you...?' 'That sort of thing' is the brutal abduction and murder of two young girls. And now a third is missing, presumably gone to the same sad end. Detective Sergeant John Rebus, smoking and drinking too much, his own young daughter spirited away south by his disenchanted wife, is one of many policemen hunting the killer.
