The guests staying at the Hotel Estoril - some actual historical persons, some imagined - provide an intriguing cast of characters to illustrate the divisions of society at the outbreak of WW2, when exiles of all kinds - refugees, spies, diplomats and aristocrats flocked to 'neutral' Portugal to escape the Nazi threat. The tone is wryly comical yet poignant, and reminded me of the quirky style of Wes Anderson's 'Grand Budapest Hotel'.
