The Earl's Shadow

WHAT or WHO IS THE 'SHADOW'?
How does it affect so many?
Charles is the Earl of Coxheath, convicted yet innocent. He spends his youth as a convict in Parramatta, only to discover he was an Earl and didn't know. He had little education and few social skills. Now faced with his own mortality, he has to work out how to live the remainder of his life after a near-death experience. He is called to step way out of his comfort zone in London. His action will change the world for many.
The echoes from the past still haunt his oldest son, Charlie. London is calling the family, and they can't put off the trip.
How does Jim, the Cobb and Co coach driver, fit in? And precisely what is the 'Earl's Shadow' that he speaks about. Can handing everything to God be that simple?
What happens if the 'Shadow' is gone?
