I've apparently read one John Dickson Carr (writing as Carter Dickson) mystery, And so to Murder, since Amazon reminds me I bought a Kindle copy for 99¢ in 2017. I'll try a re-read, but Carr seems to go for the puzzle and locked-room mystery, and that variety doesn't appeal to me.
Among those who wrote as Ellery Queen is Jack Vance, my all-time favorite science fiction and fantasy author, who did three EQ mysteries. I haven't read them, though.
There are a number of good blogs devoted to golden-age mystery, and one of the best, well-informed and entertaining, is The Passing Tramp.
