Claire writes: Billy Boyd is starring in a new series on BBC4 called “Empty”. It’s about “Jacky and Tony …just two ordinary guys, spending their days rummaging through the empty flats of people who have departed.” There are more details on the BBC website. You can see the first episode on the BBC iPlayer site for the next five days. The rest of the series should be available on BBC iPlayer for seven days after each transmission (Thursdays at 10.00pm GMT).
