Mysterious Devices

Margrethe Amelia Linden (Daisy to her friends) is a young woman of gentle upbringing, some talent as a watercolorist, and firm opinions that often get her into trouble. Determined to find her missing father, in the summer of 1895 she sets out for the last place he was seen: the Wild West. It's a rude shock when her younger sister stows away on the airship - such behavior no doubt the result of her unsuitable friendship with Maggie Polgarth and the Carrick House set.

Daisy Linden and her sister, Frederica, arrive by airship in Santa Fe, capital of the Texican Territories, determined to search for their missing father. But two surprises await them - the authorities' baffling refusal to help and a not-so-chance meeting with snake-oil salesman William Barnicott. To their joy, the Lindens find that their father has indeed been seen in Santa Fe. To their horror, it was an assignation with a cancan dancer in the dead of night.

Daisy and Frederica Linden have tracked their missing father to Bodie, the most dangerous town in the Wild West, where bad men murder without guilt and single ladies are as rare and valuable as gold. Here they must depend upon the help of the society of absent friends, that secret network of boardinghouse keepers who know everyone's business - and make secrets their stock in trade.

Hot on the trail of their missing father, Daisy and Freddie Linden step off the airship Iris in San Francisco de Asis. At the moment they discover their best clue to Papa’s whereabouts, an earthquake levels the city—and a disaster is the best time for a political coup. The forces of evil have two targets: May Lin, the river witch, and Carlos, the country’s handsome young ruler. She is sucked alive into a crevasse, having never told the prince she loves him. Carlos is abducted—with Freddie the only witness.

Daisy and Freddie Linden and their friends arrive in Port Townsend, only to be arrested as spies and brought before the most feared man in the Wild West— “Hanging” Judge Wilson Bonnell. But the unexpected intervention of an old friend plucks them out of the frying pan and tosses them into the glittering whirl of local society, where Freddie wonders if she could be in love at last. But they’re still standing too close to the fire—when a long-sought and familiar figure is spotted on the beach, bending over the lifeless body of the judge.

Daisy and Frederica Linden, having finally found their beloved father, Professor Rudolph Linden, are on the last leg of the journey they began so long ago. The only thing now in their way is the notorious gang of air pirates who haunt the archipelago between Port Townsend and Victoria. Corporal Kent of the Royal Canadian Airborne Police gallantly offers to escort their conveyance in an official airship, hoping against hope that Freddie will fly with him and give him an answer to a very important question.
