Virginia Hennypenny has worked hard to prove she could fit into a man's world, running her construction company. Her well-ordered life is shaken when she receives a key with an accompanying riddle for her birthday from Margie, her late, eccentric grandmother.

The key to the past isn't always pleasant, but the mystery must be solved to prove one's innocence. Even if you can't hold the answer in your hand, it can be right in front of you. The slow hand may not be yours, but your heart will recognize the treasure of love it will hold.

Does the key open a door, or a box, or is it a symbol for something? Her older sister Matilda faced the same questions. Virginia has two months to solve the riddle until her next sister's birthday.

Stuart Anderson takes pride in running his construction and restoration company. He was given a mind-controlled prosthetic hand after losing a hand in Afghanistan when an IUD went off.

When the historical society announces the restoration of one of Beacon Pointe's most historical but haunted locations, he submits a bid. Stu anticipated Virginia Hennypenny would be his competition. They've been butting heads since high school.

They must get beyond their competitive streak when forced to work together. When bodies are discovered in the walls, they'll need the supernatural's help to solve the murders.
