Young writer Agatha Christie, bruised from her divorce and struggling with fame and success, travels to Baghdad, only to be caught in a web of murder and intrigue. She finds herself mired in the decadent core of the ex-pat community, where rival archaeologists, spoiled funders, bored partners, the downtrodden support staff and the upper-class all co-exist in a hotbed of rumour, feud and scandal. Lyndsey Marshal stars in an alternative history period drama, set in the winter of 1928
