Murder in Mesopotamia.

One of Christie's earlier and very popular titles; she was inspired from her own visit to the Royal Cemetery at Ur where she met her husband, Sir Max Mallowan, and other British archaeologists.

Nurse, Amy Leatheran, is hired to care for Louise Leidner by her husband of two years Dr Erich Leidner, a Swedish archaeologist. They are on a dig near Hassanieh, Iraq, then a British protectorate. Louise was married briefly during the Great War 15 years earlier to a German named Frederick Bosner, who worked for the US State Department but was actually a German spy...the foundation for another case involving Hercule Poirot.
