Mallowan was Director of the British School of Archaeology in Iraq from 1947 to 1961. In 2007 this was renamed British Institute for the Study of Iraq (Gertrude Bell Memorial). He was the second husband of Agatha Christie. She accompanied him on many of his digs.
She published They Came to Baghdad in 1951. It doesn’t have an archaeological setting, but Murder in Mesopotamia (pre-war, 1936) had been set against the background of the excavations at Ur, where Mallowan had been the assistant of Leonard Woolley.
The Nimrud ivories in Iraq were damaged when the museum in Baghdad was ransacked after the illegal invasion. Those which had been held back by the British Institute had been in storage in the UK and never exhibited (why not?). The Institute has donated a third of its collection to the Museum and sold it a further third. It will give the rest to Iraq.
