How was Solomon lured away from his home and kidnapped? Explain.

Solomon Northup is a free black man living in upstate New York with his family in the 1840s. He is a carpenter and a talented violin player. One day, two men approach him and ask if he will accompany them and play his fiddle as they travel to Washington DC to the circus they work for. Solomon agrees. Unfortunately, he is drugged and wakes up in what he discovers is a slave pen within view of the Capitol.
