Copies of Earl Spencer's Unpublished Diana Memoir Stolen in Netherlands

Four copies of the Dutch-language edition of Earl Spencer's unreleased memoir about his sister, Princess Diana, were stolen from a truck in the Netherlands, Anadolu Agency reported.

The book, titled "Swan Song: Diana, My Sister," had not yet been published globally at the time of the theft, according to the report.

Anadolu Agency said the stolen copies were taken just days before the book's scheduled international release.

Details on the circumstances of the theft, including where and when it occurred and whether any suspects have been identified, were not specified in the report.

It is not yet known whether the theft will affect the planned release schedule for the book in other markets, according to the available information.

Earl Spencer, the brother of the late Princess of Wales, has previously spoken and written publicly about his sister, who died in a car crash in Paris in 1997.
