Two barges moored side-by-side in a canal are destroyed by fire, and Banks knows the devastating blaze is no accident. On board one barge, a young junkie girl perishes. On board the other, an odd and secretive artist is burned beyond recognition. Not long after, another raging inferno engulfs a trailer and its occupant. Before the body count can climb any higher, Banks must determine whether he's dealing with a serial arsonist or with a far more devious individual who is lighting fires to incinerate evidence of further crimes.
