It's driving me nuts! Things like this get stuck in my head and keep me preoccupied until they're solved. I should never click on anything that says "anagram".
I've been thinking on it from other angles -- book titles from the 50s that might work --
What was the name of the "Man in the Gray Flannel Suit"? Nope.
What was the name of "Lady Chatterley's Lover"? Nope.
What was "My Cousin Rachel"'s last name? Nope.
And so on and so forth.
