Disclaimer: Tamara Pierce is an all-out genius. If I were her, I would be extremely rich right now and writing my own books and not writing stories on fanfiction.
When tailing a suspect, hide in plain sight. It is best to wear nondescript, but certainly not ratty clothing. Never wear bright colors or frills. Frills are both distasteful and noticeable, avoid them if you can. The best disguise for any girl to have is a simple maid's outfit. Maids can be anywhere because maids are supposed to be doing jobs all over the place. If you happen to be searching a study for some treasonous papers and someone walks into the room that you are, you could always say that you were just dusting and accidently tipped something over and the reason that you fingers were all over one of the master's private files was that you were merely cleaning up your mess. Tailing someone in the market? All anyone would possibly see from you is a young maid buying something for her mistress or house. The only trick you'll actually have to learn is how not to get caught.

Author's Note: This is the beginning of my new story and first Tamara Pierce fanfic. Sound anything like what Aly would say to her budding spy of a daughter?
