Another good read is When the Word is Given by Louis Lomax. Lomax's book is full of insights about the structure of the Nation of Islam and smart profiles of Elijah Muhammad and Malcolm X several years before Malcolm was suspended.
There is one curious passage in the book. Nowadays many us believe that John Ali, National Secretary of the NOI, was an informant for the government. Ali, I think, was also the one who reported Malcolm's "chickens coming home to roost" statement to Elijah Muhammad. On page 82, John X (John Ali) is mentioned casually by Lomax as a "former FBI agent." Apparently no one at that time thought that being a former federal agent disqualified said person from sensitive NOI posts. AMAZING. Kinda hard to believe in retrospect. FBI Lomax died in a car accident while working on a film project implicating the FBI in Malcolm X's assassination so he likely figured out that John Ali was a spy at some point. Many believe Lomax might have been killed by the government.
For a fascinating account of what it was like coming of age as a daughter of Malcolm X, see Ilyahsah Shabazz's memoir, Growing Up X. Ilyahsah is Malik (Malcolm) and Betty Shabazz's third daughter (they had six children, all girls).
Make it Plain
Make it Plain is one of my favorite documentaries on Malcolm X. Great footage of Wilfred Little (a senior brother of Malcolm), John Henrik Clarke, Alex Haley, Sonia Santchez and much more.
