When author Ron Arons found out that his ancestor served time at Sing Sing, one of America's most infamous prisons, he faced a dilemma: should he tell people or try to keep the information a secret? He chose the former - and the more he learned about his criminal great-grandfather, the more fascinated he became with what had led him to commit the crimes that eventually landed him in jail. Soon after, Arons decided to expand on the topic by exploring the lives of all Jews who served time in the famous prison, resulting in a fascinating history of New York crime.
