What did the prisoner do in the last two years of his confinement?was he left free from the prison ? what actually happened in the end ? did anyone...

The prisoner, a young lawyer, spent the final two years of
confinement reading. He read books on topics such as philosophy, religion, science,
literature, and medicine. The banker recounts that the young lawyer read avidly and
voraciously, incessantly moving from text to text. Apparently, the lawyer has resolved
to survey the span of accumulated human knowledge.

Your
second question asks if the prisoner (the lawyer) was set free. The lawyer had been free
to leave at anytime during the fifteen years. He would, of course, have to forfeit the
two million dollars. Because he researched the wisdom of the world, he determines that
despite any human success or accomplishment, life is futile. He states that mice and men
have the same fate because they all eventually die. He no longer values money or
achievement, so he leaves the lodge a few hours before the fifteen years end. Neither
man dies.
