Tutankhamun's mummy
Detective Michael R. King and FBI profiler Gregory M. Cooper came together with an actual Egyptologist to form their own theory which was that Tutankhamun was murdered. With the use of forensic evidence and their extensive backgrounds in criminology, they came to the conclusion that he was likely murdered by one of his closest advisors, Ay. Ay did succeed Tutankhamun on the throne, so they used that as the motivation for the murder.
Bretby Hall
Following the death of the seventh Earl in 1871, the Estate passed to his widowed mother, Anne Elizabeth, Dowager Countess of Chesterfield (1802–1885), whose good friend, Benjamin Disraeli, paid frequent visits to Bretby. On the death of the Countess, her estates devolved upon Lord Porchester, the eldest son of her daughter, Evelyn (died 1875), who had married Henry Herbert, 4th Earl of Carnarvon in 1861. The 5th Earl of Carnarvon, the famous egyptologist for whom Howard Carter discovered the tomb of Tutankhamun, commenced breaking up the Bretby estate during World War I. The Carnarvons never lived at Bretby Park, preferring their home at Highclere Castle, near Newbury, Berkshire. They did make regular visits, however, particularly for shooting. The main estate was sold to John Downing Wragg, a Swadlincote industrialist. The proceeds helped to fund Carter's search for the tomb of Tutankhamen in Egypt in the early 1920s.
