Dead Secret by Devaney Catherine

I fantastic book, thoroughly enjoyed it.

‘Growing up wasn’t a process; it was a moment. It was the moment I watched Daddy die. Everything began to unravel then.’ When their father dies of a sudden heart attack, sisters Rebecca and Sarah Connaghan set aside their differences and return to the family home in Glasgow. Then Rebecca finds letters between her father and the mother she barely remembers that cast doubt on everything she’s been told about her family. Reeling from confusion and grief, she sets off alone for the remote Highlands village that may hold the key to the past. Above all, she is determined to prove the innocence of her father – the beloved, silent man she once thought she knew, now accused of a terrible crime.
