Their rotation in robbery is up, Frank and Tim return to the homicide unit. They find that citations are being handed out to the unit and a delighted Gee, whose clearance rate is the highest it has been in five years. Kellerman and Lewis are also scheduled to return. Howard is still on assignment with the fugitive squad. Additions to the unit through rotated assignment include Det. Ballard who actually comes from a Seattle homicide unit, Det. Falsone and Det. Gharty. Falsone and Gharty worked with the unit on the Felton case last spring; however, nothing is mentioned about the status of that case. (Sharp-eyed viewers note that Felton's name is still in red under Pembleton's name on the board.) Meanwhile, Gee attends a black tie function honoring Felix Wilson, a respected member of the community. Because he grew up with them, Gee sits at a table with Felix, his wife and their family. Everyone attending the function at the hotel is kept late because the body of a woman is found dead in t

While Pembleton is still interested in the housekeeper's ex-boyfriend, Ballard still thinks that the Wilson family needs to be looked at more closely. Also, a body is found at Camden Yards during a game between the Orioles and the A's. Falsone questions Stivers about the Mahoney shooting and that begins to make her nervous. Tensions mount because there appears to be a leak to the press within the unit about the Wilson case. Orioles' security wants the case quickly resolved. Munch and Kellerman have only 48,000 possible suspects. The victim is discovered to be a dead Yankees fan. Tim gets his old high school French teacher to help them check out the whereabouts of the housekeeper's ex-boyfriend. He is cleared because of his current incarceration in a Haitian prison, which leaves the Wilson men as more probable suspects. Are Gee and Pembleton protecting Felix Wilson because he is a prominent businessman in predominately black Baltimore, as outsider Ballard suggests? Munch and Kellerman g

The Wilsons go on television to offer a reward. The newspapers are making the Homicide unit look bad and Barnfather wants quick resolution to the case. The man (and his wife) who gave up Junior Bunk are murdered; Falsone and Lewis investigate. The only survivor, their young son, is brought in to find out what he remembers. His memories-- and a recorded phone message-- lead Stivers to believe a former member of the Narcotics unit is involved. The officer cops to a deal that implicates Georgia Rae Mahoney, though Giardella doesn't want to pursue that yet. Falsone's questioning of the Mahoney shooting leads Cox to doubt her actions at the time of the investigation. Incriminating evidence leads the detectives to Hal Wilson being their prime suspect. Frank goes to interview Felix and Hal Wilson; son and father confront some long-standing issues. Hal's confession is inadmissible in court, the Wilsons leave the Baltimore area, and the case remains officially open.
