Killer on the Kelvin Explorer

Addison Harper and Sergeant Jake Murphy are off to a shaky start with their new living situation. So, when Addison has the chance to get out of town and clear his head, he’s quick to climb aboard.

The day’s scenic railway journey features a powerful steam engine pulling lovingly restored heritage carriages. On the train, passengers enjoy dramatic landscapes and endless cups of tea. When it comes to driving Milverton’s tourism, Addison can see they’re already on the right track. Unfortunately, a death en route threatens to derail not only the day’s excursion but any future marketing efforts.

Passengers have been promised an unforgettable day out – and they’re going to get it.

Killer on the Kelvin Explorer traverses New Zealand’s picturesque lower North Island and is the latest in a wonderful cosy mystery series. Investigate The Milverton Mysteries for a chaotic cast of local busybodies, delicious baked treats, a demanding and disdainful ginger cat, a very slow-burn romance with a rather appealing policeman, and of course… murder!
