Speaking about that book about the Bronzeville/Chicago numbers racket; I have it too, there is an episode I am searching information about:
In 1939 Walter Kelley's 2 lieutenants, Garland Davis and Cornell Roberts, were killed in Hot Springs by hitman Herbert Houston. Their friends retaliated by sending a hit squad after Houston, so he ran into a police station and confessed both murders, so he would be safe in prison from the retaliation. However, the narration of the episode stops here. Does anyone know what happened later? How many years did Houston get or did he recant his confession in court? When I type the names of Herbert Houston, Cornell Roberts and Garland Davis, nothings comes up on google, not even one article.

Willie Marfeo to Henry Tameleo:

1) "You people want a loaf of bread and you throw the crumbs back. Well, fuck you. I ain't closing down."

2) "Get out of here, old man. Go tell Raymond to go shit in his hat. We're not giving you anything."
