S5·E15 Wu's on First?

A new Baltimore Sun reporter gets into the middle of Frank's investigation of the death of a county cop who was shot because of drugs. Gee likes her style. Mike's brothers, Drew and Greg, come to town, who want to take him and his boat to Miami to set up a charter service. Mike learns that they are on the run from a bookie that Drew owes $18,000. To pay that debt, they've stolen Babe Ruth's Baltimore uniform from another bookie with the intent of selling it. Lewis and Cox go in search of the Kellerman boys. They find them in jail where they spent the night after trying to return the uniform.
