In the famous photograph of the assassination of Martin Luther King Jr., one man kneeled down beside King, trying to staunch the blood from his fatal head wound with a borrowed towel. This kneeling man was a member of the Invaders, an activist group that was in talks with King. But he also had another identity: an undercover Memphis police officer reporting on the activities of this group. This kneeling man is Leta McCollough Seletzky’s father. Marrell McCollough was a Black man working secretly with the white power structure, a spy. This was so far from her understanding of what it meant to be Black in America, of everything she eventually devoted her life and career to, that she set out to learn what she could about his life, his actions and motivations. What would she uncover about her father, who went on to a career at the CIA, and did she want to bear the weight of knowing?
