Crossover Cover: Hard as Nails

In this novel, P.I. Joe Kurtz tells his ex-girlfriend Rigby King, “My mother was a whore. I didn’t see much of her even before the orphanage. Once when she was drunk, she told me that she thought my old man was a thief, some guy with just one name and that not even his own. Not a second-story guy, but a real hardcase who would set up serious jobs with a bunch of other pros and then blow town forever. She said he and she were together for just a week in the late sixties…She said that he never wanted sex except right after a successful job.” The implication is that Kurtz's father is Parker, a professional thief appearing in novels by "Richard Stark" (Donald E. Westlake.) The Parker novel Plunder Squad shares a scene with Joe Gores' DKA novel Dead Skip, with the same scene being shown from the POVs of the respective authors' characters.
