Was rereading Lovecraft's complete works the other night, and am astonished I'd never caught this before (and now feel inestimably stupid).
"Get the hell out of here ya mug" 😂
The Hoard of the Wizard-Beast (which I just found online! That screen cap is off the Kindle App, as I have it on my Paperwhite).
If you encounter any other reversal/anagram gems like that, LMK - I'll be looking for more myself, now.
I honestly don't recall ever reading anything wherein HPL divulged doing stuff as I found above, though this could be due to a deficiency in my knowledge.
@netspionage thank you. I’ll have a look in my complete lovecraft
