Owen Marshall, Counselor At Law

The Desertion of Keith Ryder (3x22)

Air date: Mar 30, 1974

Will is an investigative reporter who goes to jail rather than reveal his source. The story: something to do with the drug death of a rock star. Susan Strasberg plays the singer who may be the source and there is a hint of romance between her and Ted, Owen's assistant. Some good points about freedom of the press here.
