When Edie Budd arrives at a shabby West London boarding house in October 1958, carrying nothing except a broken suitcase and an envelope full of cash, it's clear she's hiding a terrible secret. And she's not the only one; the other women of 73 Dove Street have secrets of their own. Tommie, who lives on the second floor, waits on the eccentric Mrs Vee by day. After dark, she harbours an addiction to seedy Soho nightlife - and a man she can't quit. Phyllis, 73 Dove Street's formidable landlady, has set fire to her husband's belongings after discovering a heart-breaking betrayal - yet her fierce bravado hides a past she doesn't want to talk about. At first, the three women keep to themselves. But as Edie's past catches up with her, Tommie becomes caught in her web of lies - forcing her to make a decision that will change everything.
