We never thought there’d be a new Jackson Brodie novel. After four brilliant mysteries (and a superb television adaptation starring Jason Isaacs), we thought Atkinson had called it a day, returning to the historical literary fiction she’s so good at. Then nine years since the last Brodie was published, out came Big Sky and the crowds all cheered.

I haven’t got my hands on the new book yet, wanting to do things properly and reread the previous four. I’ve had them there on the bookcase waiting for a special occasion. So I picked up Case Histories thinking, I know what happens so will I still enjoy it?

The story gets off to a fairly gentle, atmospheric start, with the setting of Cambridge during a summer heatwave, following a family of young girls, the elder three doting on the youngest and sweetest, little Olivia. Then the unthinkable happens – little Olivia goes missing.

Thirty years later, Olivia’s sisters, Amelia and Julia, make a discovery that prompts them to hire a private detective. Enter Jackson Brodie – ex-army and-ex police and with a ton of baggage regarding his ex-wife, his eight-year-old daughter, to say nothing of the tragedy of his childhood.

Two more cases hit Jackson’s books at the same time: a grieving man haunted by the murder of his daughter ten years before; a woman who has lost touch with the niece she promised to look out for when her sister was arrested for killing her husband.

The cases shake Jackson out of the stupor that has beset him as he spends long days surveilling an air hostess on behalf of her jealous husband and being at the beck and call of a crazy cat-lady who neglects to pay him. Through the book, someone seems intent on killing Jackson, so the story is livened up by several fights.

Not that it needs enlivening as the story sparkles with humour and terrific characters. They are all notable for various reasons: Mr Wyre’s devotion to his dead daughter mirrors the powerful bond and fear Jackson feels over his own daughter, Marlee, who at eight is pert and has a habit of blurting things out at the wrong time. Julia and Amelia are eccentric opposites – Julia’s outrageous flirting adding to the humour of the book, contrasting with the awkward spinsterishness of her sister. Binky, the crazy cat lady, is a treat for her old colonial airs, and has an odd connection with the sisters and the secrets surrounding them.

I loved this book a second time around. Having finished it, I could pick it up and start it all over again – it was that good. Being character driven rather than plot driven, Case Histories is nevertheless a complete page-turner. The prose is all you could wish for too – smart, witty and honed to perfection.

And then there’s Jackson. He’s an archetypal sleuth – troubled, with a messy past; he’s clever but gets into scrapes through his dogged determination to keep digging. And he’s got that Yorkshire no-nonsense manner that makes relationships with women difficult as he struggles to articulate his feelings (while women readers find him totally gorgeous). It’s no wonder Atkinson brought him back for more outings and even after nine years, the new book’s popularity would suggest he’s a welcome return. Case Histories is a rare five star read from me.
