Nat and Abigail have decided that Canada is their best bet for a clean start with their new baby. It’s the place where American and Scottish accents go relatively unnoticed, and newcomers can get lost in a crowd. The problem is that Canada doesn’t have a transcontinental train, so they have to sneak back into the USA to get to the West coast.

They catch a night train heading over the mountains, and are delighted to find it’s one of the new Palace cars, designed to allow people to sleep, and get the remote areas behind weary travelers. The train is packed full of English butlers heading west to join a new employment agency. They hope to make a fortune providing the New World nouveau riche with the Old World class, which they are desperate to buy for their children.

When the train is stuck in a rock fall, they find that a woman has been attacked in the night, and her moonstone stolen. Our heroes decide it’s best to solve the mystery rather than face too many questions.

They unravel a mystery which has evil tentacles reaching across oceans. Will they be caught up in them too?
