When Emily ‘Fido’ Faithfull bumps into her old friend Helen Codrington, quite by chance, it feels like destiny. The two women haven’t seen one another for years: their once-close friendship came to an awkward end seven years ago, just before Helen and her vice-admiral husband moved to a British naval base in Malta. Now it’s 1864 and sheer good fortune has brought them together on the streets of London. Of course they have changed. Fido has become a passionate reformer and supporter of social justice, earnestly devoted to her work at the Victoria Press. Helen is… well, Helen. Just seeing her again brings the light back into Fido’s life. She is light and cheerful and colourful and perhaps a tiny bit frivolous, but that’s how she’s always been. One thing does trouble Fido, though, and that’s the Scottish Colonel Anderson who seems in such close company with her married friend. When Helen begs Fido for help in dealing with the Colonel’s attentions, Fido leaps to the rescue: to feel needed again, by Helen, is a thrilling feeling. Soon, however, Fido begins to realise how shabbily she has been tricked, and her association with Helen may prove to be her undoing.
