Apprehending

You've seen the plot before. The local police have been told not to apprehend a criminal but keep him under surveillance because Interpol want to catch the whole network. But an ambitious, impetuous young cop who's unaware of the big picture arrests the criminal because he thinks the criminal's getting away.

Apprehending a poem can have the same plot. Committing yourself to the first interpretation ensures that you get the bird in the hand, but you might miss out on many more that two other possibilities in the bush.

So follow at a distance. Wait for it to make contact with more significant agents. Try to picture the whole network. The first idea you have may be the easiest to find because it's the most superficial. Don't think that the title says it all. Don't think that the rhymes are what it's all about. Remember that even low-level operatives are cunning enough to lead you down blind alleys.
