In high school Danny Donohue had been one of Joe Polito's best friends, but Joe hadn't seen him or spoken to him in 15 years - not since an arson fire killed Danny's mother and he ran from the horror to a new life in California. When Danny walks into the Old Town Tavern and asks Joe to help him find whoever set that fire, Joe cannot say no. But, even after 15 years, Joe knows Danny. He can tell that Danny's not right; he's hiding something. Danny says that solving the 15 year-old mystery will free him from his tragic past, but Joe knows that's only part of it. Solving the crime will mean nothing unless Joe can uncover Danny's secrets and help him redeem his future. In Somerville, that's what friends do.
