Shadowed Gold by Alice Fox Parry

It was more than two months later that Valerie and Katherine were watching the sunset over blue mountains as they walked along the promenade on the cliffs of a little Tasmanian seaside resort. They had been married just a week, and had resolutely put behind them the tragedy that had made such forceful entry into their lives.

The last few weeks had been most unhappy ones. The inquest into the deaths of Gardiner and Delamere had meant publicity of a most trying kind, and when it was over they had wanted to get right out of the world and hide their heads from those who had known them, where they would not be pointed out to everyone as the central figures of a notorious scandal. One thing had been kept secret, and the gold discovery had not been proclaimed until Crandall's claim had been fairly established.
