Arvin Markley is a thin man with red hair and pale blue eyes. He is dressed in western-style clothing that is dirty, worn, and patched. He has a nervous and furtive manner, constantly glancing around and avoiding eye contact. He has a gaunt and haggard appearance, as if he hasn't had a good meal in some time. His movements are quick and jerky, and he seems ill at ease. He carries himself as if he is trying to blend in and go unnoticed.
