"There was a movie titled The Internecine Project ... with James Coburn as a chairman of the Council of Economic Advisers who gets a bunch of people to kill each other to hide his evil past. Sounds good to me, but the movie was terrible." -- Paul Krugman, 9 August 2018

I don't think you can count the Marshall Jevons' mystery series, since that is a pen name for two economists.
