Detective Harriet Blue Books in Order

Detective Harriet ‘Harry’ Blue is introduced as Sydney’s top sex crimes investigator, all sharp elbows and sharper tongue. She grew up in foster care protecting her brother Sam, and that fierce loyalty becomes the spine of the series when Sam is arrested for a string of murders that Harry is sure he didn’t commit.

In Never Never, Harry’s bosses decide she’s too close to the Georges River killings and too explosive for the press. They exile her to a uranium mine in the Western Australian desert, officially to look into three missing workers, unofficially to keep her away from Sam’s case. Bandya Mine is isolated, rough and simmering with secrets, and Harry has to build an uneasy partnership with local detective Edward Whittacker while wondering who she can trust.

Fifty Fifty finds Harry banished again, this time to the tiny outback town of Last Chance Valley after she loses her temper at her brother’s trial. Someone has left a diary on the roadside that describes plans for a mass killing, and deaths begin as soon as she arrives. While Harry races the clock in the desert, colleagues back in Sydney—especially Tox Barnes—keep digging into the case against Sam, testing her faith in the brother she’s spent her whole life defending.

In Liar Liar, grief tips Harry over the edge. Convinced that serial killer Regan Banks is responsible for destroying her family, she goes rogue along Australia’s south coast, hunting him outside the law even as the police now want both of them. The book is part manhunt, part psychological duel, as Harry pushes herself to the point where she’s not sure she likes the person revenge is turning her into.

Hush (also published as Hush Hush) begins with Harry stripped of badge and freedom, trying to survive as inmate 3329 in a women’s prison where former cops are prime targets. Deputy Police Commissioner Joe Woods, the man who put her away, arrives with a poisonous bargain: his daughter and toddler grandson are missing, and if Harry can find them, he’ll consider setting her free. The search drags her back into a world of corrupt power, old enemies and hard choices.

Harriet is stubborn, loyal and often her own worst enemy.

Across the Detective Harriet Blue novels, co-written with James Patterson, readers get a mix of outback noir, city procedurals and high-octane chase scenes. The ongoing mystery of Sam Blue threads through each case, but every book also stands as a self-contained thriller with big moral questions about justice, family and how far one detective will go when the system fails.
