1925. A cemetery on a hill in Illinois. A strange notebook locked away in a drawer.

Mysteries abound, and your only clues lie in the epitaphs etched into each gravestone. They tell the story of the small town through the final traces of its residents, now resting six feet under. Using observation and deduction, you will soon realize these graves are not as silent as they initially seem… -description from the publisher
