Dr. Clay Goodman / Leonard Yadder

An obese, self-centered engineer who misrepresents himself as a credible geneticist, is Kuhn.s despicable traveling companion and master of the stolen Flash Weapon prototype.

Yadder has an essential role as the only person with the technical expertise to operate the devise. He is driven by his hatred of General Harper, but is unaware that his nemesis is the very man manipulating him throughout the book.

His death represents the first opportunity for readers to truly experience the monster's fury. Yadder's only redeemable quality is his ability to briefly thwart Finch's wrath, surprising the stealthy assassin with six rounds from a snub nose .357. Nevertheless, his fate is inevitable and further acts to exemplify the thoroughness of Harper's plan.
