So the book is called The Cuckoo's Calling.
Now it says it's by Robert Galbraith but if you're a reader, or just so happen to know, you would then know this is the pseudonym for J.K. Rowling. It's also book 1 in a 3 series of stories called the "Cormoran Strike Series". I do know from reading the inside of the cover and some slight research on the series that Cormoran Strike is the name of the detective in the storyline.
