This was a fun story, and I loved the twist at the end. I'm a huge fan of modern twists on ancient mythology, and this was a good one. I also like how simple and straightforward the narrative was.

One thing that stood out to me was the expository mention of the hundred thousand dollars. While I think that information is useful to the narrative, it feels kind of stuck in there arbitrarily and I can't help but think there might be a better place for it.

Also, I think some additional context for why the Medusa's head was desired by Alan and Zach's employer would be helpful. It's such a unique item, I was hoping for a little more backstory to explain why they were after what they're after, and why it seemed, based on Perseus' comments at the end, that this wasn't the first time that someone had tried to steal the item. If that's the case, what's the story there?

Overall, this was a fun story and I thought you did a good job with it. But whenever a story comes in significantly under the word count of the contest it was created for (in this case, yours was 307 words in a contest with a maximum of 1500 words), I can't help but think that some of that extra space could have been utilized to round out the story a little. Other than that, though, this was a fun read. Nice work!
