Jury of One (2x8)

Mike's old friend Patricia Tyler calls him for help when neighborhood hoodlums vandalize her father's grocery store. Mike sides with the hoodlums since her father was the vote that hung a jury in the murder trial of Mike's nemesis, Sam Mayo, a gangster who Mike believes killed a friend of his. When the assistant District Attorney decides to drop the case because several witnesses develop amnesia, Mike starts his own investigation - with surprising results.
