Mary Howe was one of the prisoners of The Lucky Buckle Mine.
Mary Howe, who was a short and stocky woman, had been sent to a prison in Canon City, Colorado for beating her husband senseless with his whiskey bottle. When the Chimera swept into Colorado, the collapsing the state government, transferred Susan and her fellow inmates to the Lucky Buckle Mine where they were forced to mine gold for the personal benefits of their corrupted handlers, led by Warden Hiram Brewster. Mary was made to mine gold in Tunnel Five along with fellow prisoner Susan Farley.
