Lethal White is the fourth outing for the fictional private detectives Cormoran Strike and Robin Ellacott and their creator Robert Galbraith (better known as J.K. Rowling).  It’s a very long and complex yarn – by far the most ambitious yet by Galbraith/Rowling – featuring a murdered politician, blackmail, and other kinds of nastiness.  It’s all great fun, not least because of the unlikely, bubbling romance between the two protagonists.  Always credible? No. But this is escapist storytelling at its best: absorbing, undemanding, and entirely seductive. What more needs to be said?
