Double Star: serialized in Astounding February to April 1956, and Heinlein's first Hugo-winner. Out of luck actor Lorenzo Smythe is shanghaied into playing his greatest role: doubling for the controversial politician John Joseph Bonforte - who has been kidnapped on the eve of a major breakthrough in relations with the Martians. Lorenzo is a prima donna with the capability - and eventually the will - to pull it off. From the first sentence, Heinlein has you hooked. (One of my favorites.)
