Jim Aparo is in his first year of work at DC when Girls' Love Stories 142 (Apr/69) comes out. The general rule with the romance comics is anonymity, and here editor Jack Miller makes Aparo even more anonymous by assigning him an overwhelming inker, Bill Draut, on the story "Thrill-Chick." (There are none of the nonconventional, angled panel borders Aparo uses on Aquaman, either.)
I started looking over the late-60s/early-70s DC romance comics in search of possible Richard Hughes scripts, but haven't run across any so far. I can see stories by Robert Kanigher, Jack Miller, and Jack Oleck, but the other writers like Barbara Friedlander, Lee Goldsmith, and Phyllis Reed (as given in the Who's Who) I haven't been able to credit with stories at this point. I'm sure there are writers not yet connected with these books. In other words, I can't ID the writer of "Thrill-Chick."
