**MIDDLE GRADER MYSTERIES GROW UP** It was late last fall, and on the cover of the New York Post was a photograph of twelve year old Jeremy Siller standing in a city park with his bloodhound, Digger. They were surrounded by crimson stained paw prints and the headline read "Death of a Dogwalker." Even by Big Apple standards, the crime is senseless, but this boy and his dog come to make sense of it, with the help of one potty-mouthed and loveable Detective Sergeant Joe Perillo. Along the way they cross paths with a Columbian drug lord, some misguided and truly dangerous gang members, and a Wall Street financial writer who has sold his soul in order to save his life. FAST PACED AND FUN READING. THINK OF IT AS COLUMBO FOR KIDS.
