Imagine, if you will, a “Mission: Impossible”-type movie set in the early 20th century. The Impossible Missions team must thwart an attempt to kidnap President Theodore Roosevelt that they know will take place at the District Courthouse at Fifth and Indiana NW.

Actually, what the team wants is to spirit Roosevelt away and replace him with a body double — one of their operatives wearing a lifelike gutta-percha mask (fashioned by sculptor Daniel Chester French, as it happens). Once kidnapped, the fake Teddy will be able to infiltrate the criminal ring, which is working at the behest of wealthy railroad magnates opposed to Roosevelt’s trust-busting.

With Answer Man so far?
