December 1903: While Wilbur and Orville Wright's flying machine is quite literally taking off in Kitty Hawk, North Carolina, with its historic fifty-seven second flight, their sister Katharine is back home in Dayton, Ohio, running the bicycle shop, teaching Latin, and looking after the family. A Latin teacher and suffragette, Katharine is fiercely independent, intellectual, and the only Wright sibling to finish college. But at twenty-nine, she's frustrated by the gender inequality in academia and is looking for a new challenge. She never suspects it will be sleuthing . . .



Returning home to Dayton, Wilbur and Orville accept an invitation to a friend's party. Nervous about leaving their as-yet-unpatented flyer plans unattended, Wilbur decides to bring them to the festivities . . . where they are stolen right out from under his nose. As always, it's Katharine's job to problem solve—and in this case, crime-solve. As she sets out to uncover the thief among their circle of friends, Katharine soon gets more than she bargained for: she finds her number one suspect dead with a letter opener lodged in his chest. It seems the patent is the least of her brothers' worries. They have a far more earthbound concern—prison. Now Katharine will have to keep her feet on the ground and put all her skills to work to make sure Wilbur and Orville are free to fly another day.
