The letter is a request from a police department for Math 225 Volan Nnanpalle to investigate the death of a circus clown named Bobo. The police have three questions: 1) whether another clown Rasterdly's alibi holds up, 2) how fast Bobo was traveling on impact, and 3) how far Bobo flew across the gorge. Volan uses the quadratic formula, formulas of dynamics, and calculations to determine that Rasterdly's alibi does not check out, that Bobo was traveling 81.4 meters/second on impact (sufficient to cause death), and that Bobo flew 240 meters across the gorge. Volan concludes it was murder rather than suicide or accident.
