1949: Agatha Christie joined her husband, the archaeologist Max Mallowan, at Nimrud, in Iraq. Christie lent a hand, cleaning ivories recovered from the excavations. She discovered that a very fine knitting needle and her face cream were “more useful than anything else for gently coaxing the dirt out of the crevices”. She used so much cream that within a couple of weeks “there was nothing left for my poor old face”.
