The Winstrop twins, Annalise and Isabel, were raised to be horse riders. They never particularly liked horses, but it came with the family. Their father, Angus Winstrop III, had competed with his brother, and their grandfather with his brother. Being that they were twins, and being that Angus was far more concerned with prize horses than his daughters, the true sport for them was tricking him into never quite knowing which of the two of them which one was actually the faster racer.
