Publisher's Summary

High school sleuths P.C. Hawke and Mackenzie Riggs quickly regret their decision to take a difficult calculus class from a tough instructor at Columbia University. But even though she's mean, Professor Dunaway certainly seems an unlikely candidate for murder. Though there are plenty of suspects, a lot of things about this case just don't add up.

Jeff Woodman's lively reading multiplies the excitement of this cool, clever teenage mystery from Pulitzer Prize winner Paul Zindel.

Solve another case with P. C. Hawke.
