A collection of short detective stories, providing an exciting new challenge for young adults who have graduated beyond the ever-popular Encyclopedia Brown mysteries series, and are interested in applying high school level mathematics and physics to solve problems. The main character, Ravi, is a 14-year-old math genius who helps the local police solve cases. Each chapter is a detective story with a mathematical puzzle at its core that Ravi is able to solve; the author invites the reader to solve the case on his or her own and then explains the mathematics used to find the solution to the puzzle.
