Although overly long with multiple suspects and red herrings, TROUBLED BLOOD is still a worthy addition to this intelligent crime mystery series. Like the previous 4 installments, this latest by Author Robert Galbraith (aka J. K. Rowling) includes many of the signature ingredients of previous stories. These include strong characterization, a twisty plot, and great storytelling. As a bonus, it also has more than 1 satisfying conclusion. TROUBLED BLOOD is definitely for mystery-lovers who like a challenge. Warning: Some portions of this book are not for the squeamish.
