Meanwhile, his wife Emma, chairman of Barrington Shipping, is facing the repercussions of an IRA bombing on the Buckingham. Some board members feel she should resign. Others will stop at nothing to ensure the Clifton family's fall from grace. In London, Harry and Emma's son, Sebastian, is quickly making a name for himself at Farthing's Bank. He's also just proposed to a beautiful young American, Samantha. But the despicable Adrian Sloane is only interested in one thing: Sebastian's ruin.
