S7·E20 Expert in Murder

Quincy is going to be testifying in the appeal of a big mob boss, Victor Ramsay, and his evidence is vital to him staying in prison. Ramsay and his people have other ideas though and have a plan to guarantee his release. They kill the only witness and then set about making sure that Quincy is discredited. Once this is done Quincy and the D.A. have three weeks to come up with more evidence or Victor Ramsay will be released.
