Authentic Life of Billy the Kid

Set in a one room shack out west at the turn of the last century, this at times funny and at times chilling play concerns Pat Garrett, the man who shot Billy the Kid. Now, many years after the famous deed, Garrett lives alone with his memories. Enter the man who wrote the dime novel that immortalized Billy and Garrett. He brings with him a man who he claims is the real Billy the Kid, now middle aged and very much alive. Is this man Billy the Kid? And, if he is then who is Pat Garrett?
