You May Never See Us Again is the definitive story of David and Frederick Barclay - commonly known as the Barclay brothers. Born poor, these enigmatic twins built one of the biggest fortunes in Britain together and spent six decades at the epicentre of British business, media and politics. Their empire, said to be worth £7bn at its height, included Littlewoods, the Ritz, The Daily Telegraph and the channel island of Brecqhou.

And yet despite their fortune and influence, the Barclays' desire for privacy meant that their story has remained largely unknown - until a very public family dispute pitched Barclay against Barclay in the High Court.

Journalist Jane Martinson unravels the fascinating story of these once inseparable brothers. Through their lives she offers compelling insights into post-war Britain, from the conditions that enabled their way of doing business to thrive through to the tightly enmeshed webs of influence between capitalism, politics and the media that shape Britain today.
