A haunted castle, a mysterious murder, and an unexpected inheritance teeming with secrets? It sounds like the perfect mystery for our delightful duo of amateur sleuths, Lord and Lady Astley.

When Frederick surprises his wife with a trip back home to America to see her family, he never expects them to be thrust into a murder mystery with Grace’s sister as the prime suspect. To add to the dilemma, a solicitor’s letter arrives to inform Grace and her sister that they are needed in Scotland immediately to claim an unforeseen inheritance left by their mother.

But with Lillias under suspicion of murder and someone else determined to keep the sisters from reaching Scotland, Frederick and Grace must use their wits and experiences to clear Lillias’s name, keep the real murderer from striking again, and claim the inheritance.

When Lillias disappears, Freddie and Grace race to Scotland, sure the answers will be found in a long-forgotten castle, but nothing is as it seems.

Even with the help of Frederick’s cousin, Blake, the ghosts of the past and dangers of the present threaten not only Grace and Lillias’s inheritance, but also their lives.

 The Highland Heist is a Freddie and Grace Mystery, sequel to The Mistletoe Countess, The Cairo Curse, and The Juliet Code.
