Sworn to Secrecy — Mary Larkin

It is 1971, and with the troubles in Belfast at their height, a happy domestic life is something that Tess Maguire yearns for. While her partnership with her friend Theresa Cunningham in a dressmaking firm is successful, it's beginning to affect her romantic interests. Theresa's boyfriend Bob always seems to be near Tess. Near enough, one night, to declare his true feelings for her. Tess has to confront her own mixed up emotions concerning Bob, as well as address her feelings for her own ever-faithful boyfriend Tony -- especially when he asks her to marry him.
