Indirection means sneakiness or lying, especially when it's deliberately meant to distract someone or divert his attention. Spies are often forced to use indirection to keep their identities hidden.
Indirection involves tricking people by making them pay attention to the wrong things. For example, magicians use indirection to distract their audiences during performances, and a politician uses indirection when he gets voters upset about one issue so they'll forget about another. In Latin, directus means "straight," and in indirection, it's combined with in, or "not." When you practice indirection, in other words, you're not being straight.
