Prince William and Prince Harry's uncle received some upsetting news as a "highly suspicious" incident sparked tensions. Princess Diana's younger brother, Charles Spencer, had vowed to "tell the truth" about one of the most beloved royals in Britain in his new book Swan Song, but a new setback seemed to stir the pot. On Tuesday, Dutch police were reportedly investigating an incident where four copies of the book were stolen just days before its release.

"Nothing like this has ever happened before," a publishing source told the Daily Mail about the theft. "This is probably the biggest book of the year and the security surrounding it has been incredibly tight," the source continued. "Every possible precaution has been taken to prevent it from being leaked ahead of its serialisation. Therefore, this unprecedented incident is being taken extremely seriously."

Swan Song: Diana, My Sister, which is set to be translated into 12 languages, had caused some concerns for King Charles as his painful past was going to be rehashed in public once again.

Diana's brother claimed that he was going to correct "untruths that have become accepted" about the late princess, which include her childhood, her unhappy marriage to Charles, and everything that happened around her unfortunate car crash in Paris on August 31, 1997.
