Ah, Treachery!, the last novel Thomas wrote before his death, tells the story of one Captain Edd Twodees Partain, drummed out of the Army and hounded by rumors of his involvement in a secret operation in El Salvador. Twodees gets hired on to help a fundraiser for the Little Rock folks recover funds that were stolen from an illicit stash used to smooth over problems and pay off hush money. Meanwhile, Partain is involved in a storefront operation called VOMIT (Victims of Military Intelligence Treachery) trying to defend former intelligence operatives such as Partain from those who are trying to cover up the past permanently.
