The third, "Desperate Highways", is a road novel.
When asked by TSR to do a "Dragonlance" mystery, he wrote "Murder in Tarsis". Roberts wrote an unpublished science fiction book called "The Line", a police procedural set in a near-future Los Angeles where the biggest racket is illegal traffic in fetal pineal glands.
