The novels are being reprinted for the 70th anniversary of Casino Royale, but now without unkind references to black people.Diamonds Are Forever, From Russia With Love, and especially Goldfinger, all have "homophobic" passages, which are now also likely censored.
I believe
Diamonds are Forever has 2 gay characters ( Villains both) who are always a couple: Mr. Wint and Mr. Kidd.
In one scene, they are shown holding hands. In another, Kidd comments that diamond smuggler Tiffany Case is very attractive "for a lady".
Also in the Novel,
From Russia with Love, The Villainess, Rosa Klebb was portrayed as a lesbian. She tried to seduce the bond girl, Tatiana Romanova in one scene.
