The Tribulations of Ned Summers

The police never make an arrest, but the town convicts Ned Summers of the crime anyway. He banishes himself to a small house in the woods where he lives alone for the rest of his life.  When he dies, he opens his eyes back in 1952, just a few days before the murder occurred.  Can Ned Summers stop the murder and save his friend?  Includes a special bonus note read by the author.
