When detective Sam Tyler was catapulted into the alien world of 1973, he could think of nothing but getting home. It was a world where men swigged scotch before breakfast, smoked fifty Embassy No. 6’s day and where birds put the kettle on. But when at last Sam got home, he realized he’d left his heart back in the seventies amongst the fly-wing collars and pints of Skol. And he missed Annie Cartwright, the woman he had fallen in love with, and perhaps – just perhaps – he even missed The Guv, that nicotine-stained, sexist, homophobic caveman who was his DCI. Now Sam is back in ’73 for good, but is this the greatest mistake he’s ever made?
