Robert Spiller

Robert Spiller lives in the beautiful city of Colorado Springs, Colorado with his wife Barbara and his daughter Jenny. His other two daughters and their children all live within shouting distance. A mathematician by trade he weaves his profession into his mysteries.

For the last thirty years, he has taught all levels of Mathematics from Elementary to College. A Calculated Demise is his second published novel and features the math teacher/sleuth Bonnie Pinkwater from The Witch Of Agnesi. Like The Witch Of Agnesi, his first mystery, A Calculated Demise uses math and math history to solve a series of murders in the small Colorado town of East Plains.
