The Ghost and Ms Cox

Life interrupted
To say the letter was a surprise was an understatement. It arrived addressed to Miss Finlay Cox, which made the contents even more extraordinary.
Orphan Finn Cox inherits a cottage. Thinks it holds the key to her origins. Of course she takes a look. Who wouldn't?
But when she gets there, she gets more than she bargained for.
Is it friend, family or foe?
