Murder at the Carnival: Mystery

Ferris Wheel at sunset,
originally uploaded by imapix.

It was in the middle of a carnival ride that I figured out my husband was trying to kill me. He'd pushed me to go on the damn ride after eating two jumbo hot dogs (I deserved them, he claimed, because I'd stayed on my diet all week long). And midway through the ride, I knew: he was trying to kill m,e. Oh, not by making me sick on the ride--I've got a cast-iron stomach, always have--I wasn't going to hurl. No, he was trying to kill me for real. I guessed it when we went through the haunted tunnel and one of the mannequins lowered the blade a good bit more than the usual. I heard a *sching* as it passed by my head, and I know that you only hear that when there's an honest-to-God blade passing by. In the light--

Inspiration: A picture of a ferris wheel on Flickr. Not this photograph, actually, but I couldn't find the one that was the inspiration and I think this one's quite gorgeous and appropriate to the mood.
Story Potential: Medium.
Notes: I find the character more interesting than the set-up, though the set-up's not bad.
