The cool and self-absorbed narrator of Laura Spinney's debut novel is a woman doctor living and working in London's East End at the time of the outbreak of World War Two. Caught up by chance in the aftermath of a bloody riot between Fascist and Communist agitators, she finds herself strangely drawn to the woman whose injuries she treats: the mysterious Anna, whose restaurant serves the best caviar in London. But this event begins a dangerous course of action which will threaten the doctor's reserved way of life, her relationship with her lover Morris, and finally her trust in human nature itself.
