'If you've missed Laymon, you've missed a treat' Stephen King

Nothing much happens in Donnerville. Then librarian Jane Kerry receives an envelope containing a fifty-dollar bill and a note from 'MOG' (Master of Games) instructing her to 'Look homeward, angel'. Jane pulls Thomas Wolfe's novel of that title off the shelf and finds a second envelope with more money and another clue...
This 'game' soon pushes Jane into crazy and immoral actions, but when she ties to quit, 'MOG' has other ideas.
