With Britain at war and London under siege from the Luftwaffe, everyone's pulling together. Or are they? Whilst bombs rained down and long-suffering Brits helped each other, some people were simply helping themselves - stealing, looting, and making money on the black market. World War II created vast opportunities for crime. Warehouses were robbed, army stores rifled and forgers kept busy providing false identity documents, ration books and clothing coupons. Looters, stealing anything of value, cleaned out blitzed houses. The blackout and bombing provided perfect cover for safe cracking and Post Office raids. Professional criminals thrived. People like Billy Hill, who despite prison terms used his wartime muscle to become, in his words, "Boss of Britain's Underworld". Complex emergency rules left normally-law-abiding citizens facing the courts. Shopkeepers who fell foul of the tangle of red tape faced heavy fines. Even as the war ended, rationing continued, and the black market flourished. Presenter Duncan Campbell unearths once-secret papers that put Billy Hill at the centre of London's organized crime in the 1950s. Using archive accounts and talking to people who were there, Campbell tells the tale of crime on the home front. With interviews from Billy Hill's son, Justin Hill, former jewel thief Peter Scott, veteran ex police officers, and historians and academics. Presenter Duncan Campbell is a former crime correspondent for the Guardian. Producer: Liz Carney A Juniper production for BBC Radio 4.
