I received an eARC of this book from NetGalley and the publisher in exchange for an honest review.

This is a fun mystery set within an alternative history (i.e., who would be the ruler of England if King Edward VIII hadn't abdicated the throne?), and I like that a character of color played the main investigator and protagonist; however, poor Jon is absolutely put through the wringer. He works tirelessly for King Eric and meticulously interviews each member of the family about his murder (making the book tedious at times, honestly), and his ending is...tough. I won't spoil it, but I felt like he deserved better and didn't care for the other characters. There are some twists I didn't anticipate, but the villains are also a little...cartoonish and cruel.
