Meet Shirley: thirteen, half-Turkish, a little overweight and obsessed with Sherlock Holmes. Oh yes, and she’s just been told she's 'on the spectrum.' Together with sidekicks Monty, Napoleon and Jasper, she starts a crime-fighting blog, aimed at her obsessive online fans, called ‘Dear Stalker…’ She’s a different kind of detective with a different skill set. She's about to surprise lots of people, including herself. And still be home in time for tea.
