"The fire at a boarded-up Catholic church raged hot and fast, lighting up Boston's South End and killing three firefighters who were trapped in the inferno. A year later, as the city prepares to honor their sacrifice, there are still no answers about how the deadly fire started. Most at the department believe it was just a simple accident: faulty wiring in a century-old building. But Boston firefighter Jack McGee, who lost his best friend in the blaze, suspects arson. McGee is convinced department investigators aren't sufficiently connected to the city's lowlifes to get a handle on who's behind the blaze -- so he takes the case to Spenser." -- Provided by publisher.
