The Crown meets Clue in this delightful locked-room mystery, sure to charm Agatha Christie fans and keep readers guessing to the end.

The king is dead. The killer is in the family. Solving this murder will be a royal pain.

The royal family has gathered at their Scottish retreat, Balmoral Castle, for a traditional Christmas. As a blizzard gathers outside and a delicious dinner is prepared, the family circles up for a holiday toast. King Eric has something momentous to say—in fact, he is about to name his successor. But as he raises a glass of his favorite whiskey, he drops dead.
 
The king has been poisoned, someone in the family must have done it, and each one of them had opportunity and motive. Eric’s beloved head chef, Jonathan, must now play detective. Why would one of the king's own family members want to kill him, and how did they do it? What happens in the castle usually stays in the castle, but this secret might be too big for these battlements. Jon is determined to expose the truth, even if it puts him in a killer’s crosshairs—and shakes the entire monarchy to its core.
