159 page mass market paperback titled THE MAN FROM U.N.C.L.E. #2: THE DOOMSDAY AFFAIR by Harry Whittington/ Ace Books # G-560, Unstated printing, Copyright 1965 (50 cents cover)/ Two dozen novels were based upon Man From U.N.C.L.E. and published between 1965 and 1968. Unhampered by television censors, the novels were generally grittier and more violent than the televised episodes. The series sold in the millions, and was the largest TV-novel tie-in franchise until surpassed by Dark Shadows and Star Trek. His name was Tixe Ylno. The U.N.C.L.E files could tell nothing about him except for that code name. He could be anyone--a cab driver, a corporation executive, a scientist, a storekeeper...ANYONE! He might be anywhere in the United States. But whoever or whatever he was, U.N.C.L.E. had to find him because he controlled a secret that had the world at his mercy! The book is complete and in GOOD - VERY GOOD condition with some overall wear. The side edge of the book has been bumped and has left a small indentation on several of the pages. The insides of the front and back covers have browned and the inside pages are tanned. (see pictures)
