Robin Jarvis was born in Liverpool, England, and studied graphic design in college. He worked in television and advertising before becoming a full-time author and illustrator. It was while working at a company that made characters for TV programs and advertising that he began making sketches of mice. From these drawings, the idea for the Deptford Mice was born. The Dark Portal, short-listed for the 1989 Smarties Book Prize in England, was followed by two more titles in the series, The Crystal Prison and The Final Reckoning. He lives in London.
