Murder Over Gold. Penrose & Pyke Mysteries, #7

Penrose and Pyke's honeymoon takes a dangerous turn when they investigate the most notorious robbery in Central Otago history. Grace and Charlie had been looking forward to a blissful break away from their hectic lives. Instead, watchful eyes follow their every move from the moment they step off the stagecoach in Clyde. Rumour has it that the Pyke family knows more about the robbery than they are telling.
With a fortune in gold still missing, and destitute miners on the prowl, the tranquillity of their honeymoon is about to be shattered. But greed is not the only sin in town. Behind the walls of stately homesteads, rose-covered cottages and kerosene-tin shacks, long-buried secrets lie hidden. One man has already been killed, and he may not be the only victim of the lust for gold. The Penrose & Pyke Mystery series is set during a remarkable period of social upheaval in 1890s New Zealand.
