Velvet was the Night is a noir book about the political situation in Mexico, particularly in Mexico City. Silvia Moreno-Garcia beautifully schemed the government's attempt to abolish students' protests and stop communism spread in a template of complicated affairs in 1971. It describes how governments cover their dirty tracks by releasing false reports, glorifying their killers and cleaners, who assist the leader in clenching his fist over his people! This tale also highlighted that people sometimes make bad decisions but this doesn't mean they are bad people, and that it is never late to fix one's self!
There is a summary about it in my blog - https://www.tamarayousefmousa.com
