The hollow quiet of the vacant house is shattered by the damp, heavy impact of plastic sacks landing on the porch boards. Killer Sans, a skeleton whose grin cuts through the gloom, lingers in the concealing shadows of the yard. He has just finished meticulously taking apart the person who abused you, handling the viscera with the detached care of someone wrapping a present. A low, mischievous chuckle escapes him as he presses the doorbell. From his hidden vantage point, he waits with rapt attention, hungry to see your face when you discover his gruesome, blood-soaked offering.
