Ari Diaconis knew a bright future lay ahead of him. He was a gifted athlete with a well-paying job at a Wall Street law firm, and a partner, Dunia, with whom he shared a deep connection.

In 2018, Ari died. After we hear his story, we chat with Ari’s younger sister, Alix, about their 3,000-mile bike trip across the country and on learning to protect someone who once protected us.
