Catalog log
Broadcast listing — not a TV Flash recap.
When young war veteran Greg Tanner (Creighton James) is found murdered in a Hudson University parking garage, Detectives Cyrus Lupo and Kevin Bernard connect the murder to law professor Kevin Franklin, an attorney who formerly worked for the Department of Justice. But when the case is brought to court, it seems Tanner may have been more affected by the war than his discharge stated. Lupo and Bernard find that the pieces start to fit when Franklin's memos from the Bush Administration are leaked. Meanwhile, Lieutenant Van Buren announces some very shocking news to her squad, concerning her health, and District Attorney Jack McCoy deals with the stress of winning the election.

Picture a Tuesday when the nation still had a cop show that split like a walnut: first the street, then the courtroom, a clang on the soundtrack that became civic punctuation. Law & Order premiered September 13, 1990, on NBC, created by Dick Wolf, and it did not invent the procedural so much as industrialize it. Prescription for Death is the template in miniature — a hospital night, a dead patient, cops then lawyers, no hug required. On the palate: newsprint, a New York that looks like a location budget with a…
