UNDERGROUND At the turn of the century, the city of Louisville was growing. There were gangs of young men in the out-lying villages, villages that were being swallowed up as the city expanded around them. Robert O'Brien had his own gang, and his fortune and influence were expanding at an alarming rate. Having learned to steal at a young age, he practiced his craft in the Portland area, where he grew up. He and his friends had been moving ever closer to the center of the city, until he was buying buildings and property in the most sought after sections. Their ill-gotten profits were being used to buy their way into Louisville society. Robert's inside information was now used to rob the richest citizens, while they wined and dined the mastermind in their homes and social clubs. Making a fortune in this manner was slow and risky, especially when he insisted on moving the stolen merchandise across the river, out of the area, to sell. What Robert and his cousin found under the city turned his gang of thieves into legends, and ghosts. He amassed a fortune that rivaled any in Louisville. How he did it and what happened to his discovery has always been a question in the minds of the authorities. Now, the legend is being revealed.
