Chris Bunch’s story gave a nod to the Reggie Rivers stories, and the result was published as part of the L. Sprague de Camp tribute anthology. The narrator, who isn’t named, tells the story of how Peter Kilgrew nearly wiped out humanity in an indirect fashion during a time safari to the Jurassic.
The stupid git was trying to wipe out all of humanity, though he was too stupid to realize it.
