Did you ever see that movie from the 1980s where Kevin Costner plays a Russian spy who has the job of investigating himself? The tension keeps building: he can’t give the job to anyone else, but the evidence keeps piling up pointing to himself. At some point, something’s gotta give.
From a review at the time:
The film makes such good use of Washington and builds suspense so well that it transcends a plot bordering on ridiculous.
That’s about right.
