J. K. Rowling's newest book, The Cuckoo's Calling, written under the pseudonym Robert Galbraith, is a marvelous whodunnit with a great main character, private investigator Cormoran Strike. As Strike digs into the mystery surrounding a supermodel's suicide, he uncovers all sorts of dirty little secrets -- and all sorts of people who want to keep these secrets hidden, no matter the cost. Strike himself is a wonderful characters: flawed, penniless, somewhat hopeless, but entirely gifted when it comes to his instincts and his professional skills. 
 The plot zips along, with a dizzying amount of details to track and decipher, and the mystery's resolution is startling yet makes total sense in light of the evidence. 
 I applaud J. K. Rowling's foray into new territory, and hope she'll continue writing mysteries centering on the memorable Cormoran Strike. The Cuckoo's Calling is quite good, and I recommend it both for Rowling's fans (adult fans, that is; this is not a book for children!) and for readers who enjoyed puzzling through a compelling mystery.
