Both Camille and Simon are NorCal residents although he hails from England, UK. Now a naturalized U.S. citizen, Simon fits the California mold of shortening things, beginning with his name (Birth name? Ask him!) and a pen name, Simon Janus, writing horror fiction (ah, the secret exposed). Camille, U.S. born, held onto her name, even after marriage, until her agents chose pseudonyms for her cozy mysteries. The Square Root of Murder, first in the new Professor Sophie Knowles series, is authored by Ada Madison, short for Camille Minichino.
