Elizabeth Eulberg is not a detective (or so she claims). She is, however, the internationally bestselling author of The Lonely Hearts Club , Prom and Prejudice , Take a Bow , Revenge of the Girl with the Great Personality , Better Off Friends and We Can Work It Out . Elizabeth lives outside Manhattan, where she spends her free time stalking English bulldogs in her neighbourhood and filling her brain attic with random pop-culture facts. The Great Shelby Holmes was her first middle-grade novel; it was followed by The Great Shelby Homes Meets Her Match. elizabetheulberg.com / @ElizEulbergMatt Robertson grew up in Suffolk and spent most of his childhood drawing and painting. He went to Art College in Ipswich and later attended Cambridge School of Art. In 2011 he moved to Norwich and began a Masters in Children's Book Illustration back at Cambridge School of Art, which he completed at the start of 2014.
