Mathematical Mystery / The Calculus of Murder / Erik Rosenthal

When San Francisco corporate mogul Bradford Melton is poisoned at a party celebrating his 55th birthday, the police assume that his spoiled daughter, who has taken up with a radical, is the murderer. She hires liberal attorney Grey Langley to defend her, and he in turn hires his friend Dan Brodsky to locate information to acquit his apparently very guilty client. But Brodsky doesn’t want to be a detective; he yearns instead to be a mathematics professor. The problem is he can’t get a job since only computer teachers are in demand, so to pay the rent he serves subpoenas for Langley and solves the seemingly unsolvable murder.
