On February 8, 2023, a sensational story came out in the news: three codebreaking enthusiasts announced that after a year of dedication and collaborative efforts, they finally had succeeded in decoding the secret correspondence of one of the most tragic characters in European history: Mary, Queen of Scots. Composed of 57 letters written in a code consisting of at least 150,000 different symbols, the correspondence between Mary and the French ambassador to England details Mary's efforts to free herself from imprisonment and gain advantage over her rival, Queen Elizabeth. After four centuries, Mary's urgent pleas can now be revealed.

A mysterious ancient city lies hidden in the mountains of Sichuan. A kingdom that was consigned to oblivion for thousands of years until the chance discovery of a jade artefact in 1929. Since that first find, more than 10,000 unusual items have been unearthed, including curiously shaped bronze heads and masks covered in gold foil. These objects may be as archaeologically important as the Terracotta Army of Xi'an, and experts think that this may be the capital of the ancient Shu kingdom.
