For a haiku this was not a real one. Mostly haiku's are about nature, for the mystery concept it wasn't really a mystery for me. This would be better if this was a short poem, with more stanzas and more words than just a haiku. Sorry if I'm being rude but I don't mean to be. This would be great with more imagery. Good luck and keep writing!

It's hard to realy review a haiku, since they are SO unbearably short. I didn't quite get it, but then there wasn't much to get. I think you did do a good job of getting your point across, which was, essentially "RUN FOR YOUR LIFE!!!!!!!!"
You must be swift as the coursing river, With all the force of a great typhoon, With all the strength of a raging fire, Mysterious as the dark side of the moon.
This is entirely off-topic, but I've now come up with an incredible idea, and I had to share it with you, considering the fact that your work inspired me. I will create a character that only speaks in Senyru/Haiku. Yay :3
Regarding your haiku, I don't think many people could relate to it, considering that not very many people have had to flee from something or someone with that sort of desperation. I agree with a post above me suggesting that you should expand this and create more stanzas. Well, there's an interesting idea for you - you could write a whole poem, with six or seven stanzas and have each stanza as a haiku.
Nowadays anything passes for poetry, so I'm sure you're not going to get shouted at for doing something different.
