A woman becomes obsessed with the story of a long-dead colonial pioneer, and her research becomes a way of coming to terms with her own past.

Researching in the archives Belle discovers the long-dead Gaden Lockyer, a colonial pioneer in Jericho Flats, and soon becomes obsessed. Belle's quest for Lockyer is her way of coming to terms with the past - her mother, 'a drummer in her own all-women's group'; her absent American father; and her ineffectual husband, Seb. In Reaching Tin River, Thea Astley's satire is at its sharpest and most entertaining.
