The first book in the Cormoran Strike detective series made me a fan— and I have three more Strike novels to look forward to.
Strike is a British private detective. Unfortunately, he and his business are a mess. Just as he gets to the end of his rope, a wealthy man hires him to investigate the death of his sister, a famous celebrity high fashion model. Everyone except the victim's brother thinks it was a suicide. Strike has a temp secretary, Robin, who helps him with the case. Their interactions make this sixteen-hour audiobook seem like a quick read (and Robert Glenister narrates with a dignified British accent).
The Cuckoo's Calling (2013) is available to read or listen to in Overdrive—and if you get hooked, you can read the rest of the series too. Also, the first three novels were adapted into a British TV show called C. B. Strike.
