The New Yorker profiles writer Michael Moorcock. Moorcock’s influence is nothing like Tolkien’s, at least on the surface, but his vision of a speculative-fiction genre that can be psychologically complex is evident in how very sophisticated some of it has become—from True Detective to Jeff VanderMeer, from David Mitchell to Under the Skin. But Moorcock also embraces the joy of pulp, and, like Tolkien, his creations are namedropped and sourced high and low.
