The Ink Black Heart

In this instant New York Times bestseller, Cormoran and Robin find themselves ensnared in another winding, wicked case as they must work to uncover the mysterious identity of an online killer--before it's too late.​

When frantic, disheveled Edie Ledwell appears in the office begging to speak to her, private detective Robin Ellacott doesn't know quite what to make of the situation. The cocreator of a popular cartoon, The Ink Black Heart, Edie is being persecuted by a mysterious online figure who goes by the pseudonym of Anomie. Edie is desperate to uncover Anomie's true identity.

Robin decides that the agency can't help with this--and thinks nothing more of it until a few days later, when she reads the shocking news that Edie has been tasered and then murdered in Highgate Cemetery, the location of The Ink Black Heart.

Robin and her business partner, Cormoran Strike, become drawn into the quest to uncover Anomie's true identity. But with a complex web of online aliases, business interests and family conflicts to navigate, Strike and Robin find themselves embroiled in a case that stretches their powers of deduction to the limits - and which threatens them in new and horrifying ways . . .

A gripping, fiendishly clever mystery, The Ink Black Heart is a true tour-de-force.

What’s it about?

Cormoran Strike and Robin Elliott are partners in a private detective agency in London. In the sixth book of the Cormoran Strike series we find Robin and Strike dancing around their mutual attraction as they try to find the true identity of an online presence that is threatening their client. When threats turn to murder the stakes just get higher.

What did it make me think about?

Robert Galbraith (also known as J.K. Rowling) writes a great mystery!

Should I read it?

I look forward to a new installment in this series about once a year. They are LONG, complex mysteries with lots of twists and turns. And although the plot is always fast- the characters are equally appealing. Can I say that I am ready for Robin and Strike to finally get together? My only other issue with this book was that the online chat threads (which are posted simultaneously on a page) were cumbersome to read. However I have no idea how this plot would have been presented without the chat threads, so just be prepared to slow down a little every few pages. This would be another book that you could easily keep a chart of characters- there are so many…. I just plowed through and ended up really enjoying this one. Don’t let the length discourage you- this is a solid mystery novel with lots to recommend.

Quote-

“The older Strike got, the more he’d come to believe that in a prosperous country, in peacetime – notwithstanding those heavy blows of fate to which nobody was immune, and those strokes of unearned luck of which Inigo, the inheritor of wealth, had clearly benefited – character was the most powerful determinant of life’s course.”

I have really enjoyed the Cormoran Strike series.......until now. I really anticipated the new book, was very anxious to read it. But, I'm sorry to say, "Robert" has lost me part way thru this book. I'm so sad at not enjoying this book. Its because of the format. I don't pay attention to all the hub-bub in the news, etc. I just read books for the books themselves, no matter what the author does or doesn't do IRL. I will read the next book, and hope I like it.

Another great Strike Story. Nice to see that our protagonists have finally figured out that they love each other, let's hope it doesn't take another six books for them to tell each other!

Oodles of odd characters. Romantic tension you can cut with a knife. Twists and turns galore. Loved the slow burn of how the story unraveled. It’s a BIG book at 1000+ pages. I wanted to know who the killer was, but I also didn’t want it to end.
