Into the stream you go.

You grab your knife from it's hip sheath and cut a length of reed from a patch by the stream and pull out the middle in order to breath, carefully lowering your body into the water. You hear the guards come closer, talking inanely about what food they are looking forward to at breakfast. You hold your body still, hoping that they won't notice you.

Luckily for you, they pass you by without noticing your presence. To keep on the safe side, you remain where you are for another minute before quietly climbing onto the bank. Unfortunately, you are now wet, and you will leave a clear water trail wherever you go.
