In November 1922, she, her father, and the archaeologist Howard Carter were the first people in modern times to enter the tomb of the Egyptian Pharaoh Tutankhamun.

[8] Lady Evelyn was launched as a debutante and presented at court in 1920,[9] with her mother staging receptions for her, including at the British Residency in Cairo during their Egyptian stays in 1921 and 1922.

From 1907, he employed Howard Carter to supervise this work including, from 1914, a systematic search of the Valley of the Kings for any tombs missed by previous expeditions, in particular that of the Pharaoh Tutankhamun.

[12] However, on 4 November 1922, Carter was able to send a telegram to Lord Carnarvon, in England at the time, saying:"At last have made wonderful discovery in Valley; a magnificent tomb with seals intact; re-covered same for your arrival; congratulations".

[13] Both were present the next day when the full extent of the stairway to the tomb was cleared and a seal containing Tutankhamun's cartouche found on the outer doorway.

[14] Lady Evelyn was also present when, on 26 November, Carter made a tiny breach in the top left hand corner of the tomb doorway, enabling him to peer in by the light of a candle.

[15] However that night, Carter, his assistant Arthur Callender, Carnarvon and Lady Evelyn apparently made an unauthorised visit, becoming the first people in modern times to enter the tomb.

Callender rigged up electric lighting, illuminating a vast haul of items, including gilded couches, chests, thrones, and shrines.

[23] Lady Evelyn and her father travelled to England in December 1922, the two returning in January 1923 to be present at the official opening of the inner burial chamber on 16 February.

[38] In July 1935 she was injured in a serious car accident on her way to Newmarket, Suffolk,[39] and recuperated in the London nursing home established by her mother during the First World War.

[48] Lady Evelyn denied the idea, later telling her daughter Patricia that "at first I was in awe of him, later I was rather frightened of him", she resenting Carter's "determination" to come between her and her father.

[56] The novel The Collector's Daughter by Gill Paul published in 2021 provides a fictional version of Lady Evelyn against a backdrop of the events at the time of the tomb's discovery.
