Dunant's first two novels were actually co-authored with Peter Busby, thus creating their pseudonym, Peter Dunant. In Exterminating Angels (1983), whether they're called terrorists or modern-day Robin Hoods, the Exterminating Angels are out to set the record straight. For them, the ends always justify the means when righting the wrongs of the world. The political thriller Intensive Care (1986) describes a chance meeting at the site of an explosion in London.

The first book to be released under her own name was Snow Storms in a Hot Climate (1987), and features Marla Masterson. Marla, a young British professor of Anglo Saxon Literature goes to New York City to rescue a friend from her drug-addled, abusive boyfriend, but not before a murder mystery ensnares them all.

Three years later, Dunant introduced readers to Hannah Wolfe, a tough and witty Private Investigator. In Birth Marks (1990), Wolfe is hired to find a missing ballerina. Unfortunately, the dancer is found by the police -- eight months pregnant and at the bottom of the Thames. When everyone but Wolfe writes off the young single woman's death as a suicide, Wolfe pushes her investigation into London's dance companies and powerful Parisian families, searching for the father. Wolfe's reputation is put on the chopping block in Fatlands (1993). Wolfe finds herself on the trail of a violent animal rights activist group after they kill the daughter of a wealthy scientist for using animals in his experiments. The novel won Dunant a Silver Dagger award for Crime Fiction. Disguised as a customer, Wolfe investigates a string of sabotage at the Castle Dean health spa in Under My Skin (1995) and soon learns that, to some, beauty is something to die -- or kill -- for.

Breaking from her Hannah Wolfe series, Dunant's next release explores the line between victim and victor. In Transgressions (1997), translator Lizzie Skvorecky is making a living translating cheap Czech thrillers into English. When the strange events of the novels seem to occur in her real life, Lizzie realizes that someone -- or something -- is tampering with her reality, and accepts the violent challenge to her sanity. Kirkus reviews describes the novel as "an unsettling, often chilling, portrait of a compulsive predator and the woman who refuses to be his prey."

Mapping the Edge (1999) also portrays a woman's unusual challenges. When Anna, a single mother, takes a short vacation to Italy, leaving her six-year-old daughter with trusted friends, no one thinks twice. Until she doesn't return when scheduled. Anna's friends and her daughter endure the painful waiting while Dunant offers two explanations of Anna's disappearance. What if Anna abandoned the responsibility of motherhood to follow a hot love affair? Or perhaps Anna's life is in the hands of a sadistic killer.

Along with writing fiction, Dunant has also edited two works of non-fiction. War of the Words: The Politically Correct Debate (1994) debates the ever-changing idea of what is "acceptable" and the effect political correctness has on Liberalism. In The Age of Anxiety (1999), ten essayists discuss their anxiety -- or optimism -- for issues such as technology, family, and the end of the millennium.

Dunant's 2004 release marks her foray into historical fiction. The Birth of Venus captures the passion and the politics of deMedici Florence in the grips of a fundamentalist religious overhaul. As the city starts to purge itself of "the low and vulgar arts," the novel's heroine, Alessandra, falls in love with a young, suffering painter. Although her family marries her to a much older man, it is mostly a dismal marriage of convenience and she has a surprisingly large amount of time to spend at the side of her true love. Intelligent and daring, Duanant has combined a love story, a thriller and a historical novel in telling Alessandra's quest to find and protect her passions.
