When a mummified foot, a pile of bones and a split skull are discovered in a Danish bog in East Jutland, the remains turn out to be a young man beaten to death about two decades ago.
Chief Inspector Tobias Lange finds himself on the trail of eco-warriors, Sami protesters safeguarding reindeer rights, and a disaffected young woman estranged from her family.
Then another incomplete set of human bones turns up, then another...
McAuley says she was inspired by Seamus Heaney's poem about the Tollund man, and she visited Denmark before starting to write the police procedural.
On her blog she also explains that McAuley is an anglicisation of her name in Irish, Róisín Nic (daughter of) Amlaoibh. "I've always understood it to be a Viking name. Amlaoibh is from the old Norse - Olaf." Hence the Olufsen pseudonym.
Her first novel under her own name, Singing Bird (2004), was a romance. Her second, Meeting Point (2007), features a CSI investigator who comes face-to-face with a cold-case murder suspect in the South of France and finds herself violently attracted to him.
Two more romances followed, Finding Home (2009) and French Secrets (2011). Besides her five novels she has also written a guide to Irish golf courses.
