A thirty-four-year-old American woman—a secret agent—is sent to do dirty work in France. “Sadie Smith” is how the narrator introduces herself to her lover, to the rural commune of French subversives on whom she is keeping tabs, and to the reader. Sadie has met her love, Lucien, a young and well-born Parisian, by “cold bump”—making him believe the encounter was accidental. Like everyone Sadie targets, Lucien is useful to her and used by her. Sadie operates by strategy and dissimulation, based on what her “contacts”—shadowy figures in business and government—instruct.

A young meteorologist checking a mountain top weather station in Kinlochleven discovers the body of a missing man entombed in ice. Cameron Brodie, a Glasgow detective, sets out on a hazardous journey to the isolated and ice-bound village. He has his own reasons for wanting to investigate a murder case so far from his beat. Brodie must face up to the ghosts of his past and to a killer determined to bury forever the chilling secret that his investigation threatens to expose.

Two years ago, a hostile Prime Minister launched the Monochrome inquiry, investigating "historical over-reaching" by the British Secret Service “to investigate historical over-reaching.” Monochrome’s mission was to ferret out any hint of misconduct by any MI5 officer—and allowed Griselda Fleet and Malcolm Kyle, the two civil servants seconded to the project, unfettered access to any and all confidential information in the Service archives in order to do so. But MI5’s formidable First Desk did not become Britain’s top spy by accident, and she has successfully thwarted the inquiry at every turn.

A man with a borrowed name steps from a flashy red sports car—also borrowed—onto the estate of his youth. But all is not as it seems. There is a new family living in the drafty old house: the Godleys, descendants of the late, world-famous scientist Adam Godley, whose theory of existence threw the universe into chaos. And this mystery man, who has just completed a prison sentence, feels as if time has stopped, or was torn, or was opened in new and strange ways. He must now vie with the idiosyncratic Godley family, and with a woman from his past who comes bearing an unusual request.

Northern Ireland, spring 1981. Hunger strikes, riots, power cuts, a homophobic serial killer with a penchant for opera, and a young woman’s suicide that may yet turn out to be murder: on the surface, the events are unconnected, but then things—and people—aren’t always what they seem. Detective Sergeant Duffy is the man tasked with trying to get to the bottom of it all. It’s no easy job—especially when it turns out that one of the victims was involved in the IRA but was last seen discussing business with someone from the loyalist Ulster Volunteer Force.
