Michael Nava, whose latest novel in the Henry Rios mystery series is titled “Carved in Bone,” is interviewed by host Richard Wolinsky. When Michael Nava began writing his Henry Rios mysteries in the late 1980s, the only other mystery writer with a gay male detective was Joseph Hansen. But Henry Rios is more: one of the first Latino noir detectives in American literature. He is also the author of “Lay Your Sleeping Head.”
