Excalibur (S18E18)

Jeweler Victor Madison is found murdered, and Detectives Cyrus Lupo (Jeremy Sisto) and Kevin Bernard (Anthony Anderson) investigate a peculiar deposit made into Madison's bank account. The deposit leads the detectives to investigate Madison's brother-in-law, Frank Beezley, who was running an illegal prostitution ring, The Excalibur Club. Closing the case proves to be a challenge, as the trial gets risky for Jack McCoy (Sam Waterston) when his job is threatened. (iTunes)
