Six garbage bags full of red cedar shavings, purchased two at a time for a dollar a bag, at midnight, at the self-serve shed at Dunstead & Daughter Custom Furniture, serving your fine cabinetry needs since 1986. No cameras, no lights, no attendant, no theft, no problem.

Getting the old man onto the bags was the hardest part. Moonie first threw him face down on the topmost bag, then heaved his feet up. The old man was tall, but frail; eighty-two years old and sedentary and semi-senile, though not so senile that he didn't know what was happening now. He sank down into the bags of wood shavings and thrashed there, got halfway off, then sank down between them, thrashed some more, then quit. Wood shavings made for the most intense fire, and left no obvious residue; or so the arson fans theorized on the Internet.

A driving rain beat against the kitchen windows. Ideally, Moonie would have preferred to trail the gas out into the yard, and to touch it off from a distance. With the rain, though, that would be difficult. The rain would wash the gas away as quickly as it was poured. So it would have to be kept inside. A small risk...the fumes boiled unseen around the killer's ankles, flowing into every nook and cranny.
