She poured tea, a habit she'd acquired in England. 'The answer is

… he doesn't know.'

'Then I suggest you fly to London and tell him,' and he returned to his New York Times.

And so, a new life began for Helen Darcy, now Lady Helen Lang, divided between the house in South Audley Street and the country estate by the sea in North Norfolk, called Compton Place. There was only one fly in the ointment. In spite of every effort to have a child, she was bedevilled by miscarriages year after year, so that by the time her son, Peter, was born when she was thirty-three, it seemed a major miracle.

Peter proved to be another great joy in her life, and she took the kind of interest in his education that her father had taken in hers. Her husband agreed he could go to an American prep school for a few years, but afterwards, as the future Sir Peter, he had to finish his education at Eton and the Sandhurst Military Academy. It was the family tradition – which was fine with

Peter, for he had only ever wanted to be one thing, a soldier like all the Langs before him.

After Sandhurst came the Scots Guards, his father's old regiment, and a few years later, a transfer to the SAS, for he had inherited his mother's ability with languages. He saw service in Bosnia and in the Gulf War, where he was awarded the Military Cross for an unspecified black operation behind Iraqi lines. And in Ireland, of course, the one place which never went away. Hand-in-hand with his ability for languages was a flair for dialects. He spoke, not with some stage Irish accent, but as if he were from Dublin or Belfast or South Armagh , which made him invaluable for undercover work in the continuing battle with the Provisional IRA.

Because of the life he led, women figured little. The odd girlfriend now and then was all he had time for. The fear was real, the burden immense, but Helen bore it as a soldier's wife and mother should, until that dreadful Sunday in March 1996, when her husband answered the phone at South Audley Street, then replaced the receiver slowly and turned, his face ashen.
