Seven Miles from Sydney by Lesley Thomson

When Deborah Carry is invited to Australia to write a film about gangland violence, she gets murdered herself. The police and the newspapers are hardly sympathetic; any woman who jogs alone is asking for trouble. When her best friend May identifies the killer they let him go. But Deborah’s death forces May to re-evaluate her own life. Back in England she realises that she was in love with Deborah, that she has always loved women and for the first time she feels strong enough to love herself.
