It was literally in the wiki you linked to lol. Though I was mistaken, it wasn’t Howard Philip Lovecraft, but “Philip Howard.”
Philip Howard, writing a lipogrammatic appraisal of A Void in his column Lost Words, said “This is a story chock-full of plots and sub-plots, of loops within loops, of trails in pursuit of trails, all of which allow its author an opportunity to display his customary virtuosity as an avant-gardist magician, acrobat and clown.”
