A man is haunted by the memory of a tramatic act which occured in an amusement park ride that he owns.

"The entrance to the tunnel had been painted to resemble a woman's mouth, with Cupid's-bow lips bordering it in vivid red. Marco stared into the yawning darkness beyond. A woman's mouth -- how often had he dreamed of it, this past winter?"
