Stephen Collins, an arsonist, sets off explosions around the city, starting with three incendiary devices in a library, with the latter two set to go off whilst firefighters are tackling the fire resulting from the first device. Obsessed with Haley, he starts sending her cryptic clues (riddles) along the way.
