- "She was a sad lady who never hurt anyone except herself."
- ―Cole Phelps
Evelyn Summers worked in the legal copyright department of Keystone Film Studios. She had a successful career despite being an alcoholic. When Keystone closed down in 1941, she lost her job and was unable to find work. As a result, she became depressed and her alcoholism worsened. Evelyn became isolated from her friends and family, although her mother tried to convince her to come home to Connecticut for treatment. At some point, her husband divorced her and she eventually ended up broke and homeless. Walter Robbins, a friend of her ex-husband, was sympathetic and offered her a place to sleep in the backroom of Levine's Liquor Store, where she also stored her meager belongings, though she often camped out at the Pacific Electric Railyard.
Evelyn spent much of her time at the public library where she met James Tiernan and Grosvenor McCaffrey. She became good friends and even lovers with Tiernan and came to greatly admire McCaffrey and his aspiring views on fixing society. However McCaffrey loathed and scorned Evelyn, his hatred for her and Tiernan only intensified and he even threatened to kill her when she stole his copy of Aristotle's Metaphysics. Her relationship with Tiernan and "friendship" with McCaffrey resulted in a love and hate triangle.
