Duga was a publisher in the former Yugoslavia that reprinted many English language mysteries and thrillers into Serbian. The company’s name means Rainbow, and this novel from Donald E. Westlake was released in 1969 as a Zeleni Dodatak, or Green Edition, with Ursula Andress on the back. We have no idea why she’s there. We assume Duga put random hotties on the rear covers to entice buyers. The text there says “to your album,” which we like to think of as a mental album, like a spank bank, but that’s just us being rude. Obviously, the term refers to one’s collection of Green Edition back cover celebs. Collect them all and win a prize! That’s right! A weeklong trip to Zlatibor! Okay, now for what we don’t know. We don’t know which Westlake book this is. Desna Ruka translates from Serbian as “right hand,” but Eda Ganoleza translates as nothing—at least on the interfaces we used. A scan of the Westlake bibliography turns up no novel containing right hand in the title. So your guess is as good as ours. Doubtless people in Zlatibor know.
