Message on the Tide

Who'd think an innocent early morning walk on the beach would yield a sealed bottle with a mysterious set of letters from decades ago?

Certainly not Darcy Harmon, but that's exactly what she's come across. 

And leave it to her sister Emma, the family's resident amateur sleuth to try to take the mystery away from Darcy. 

Well, Darcy's having none of it. It's her mystery to solve and she's not sharing it. At least, not until someone tries to take her life. Twice. 

Now, she's suddenly open to having some help to find answers to the questions spawned by the mysterious messages in the letters that washed in on the tide.
