The first policeman on the scene noticed many strange things about the body.
For one, it was oozing green. Bodies rarely do that, not bodies this fresh. For another, there didn't seem to be a head involved. And while there were legs and arms – or at least arm-ish and leg-like appendages - he counted ten. Not the more usual two of each.
As more police swarmed the scene, taping off and photographing and putting things in little bags, they noticed stranger things. The dead Hydra – for Hydra it was (or had been) - wore a tailored suit. They found a Registered Mage card in a pocket. They assumed the card was his but he was hard to identify from the photo of his face with his entire cranium missing. The neck was a dead ringer, though. The unchewed bits. And this was the first Hydra anyone had ever seen wearing anything. Or carrying anything beyond bits of waylaid victims. Or who had not survived decapitation by growing two more, very annoyed heads.
The moment Inspector Willis arrived on the scene, she swore. The information she'd received from her superiors as to the body's probable identity was confirmed with just a glance at the victim.
She knew what she was going to have to do.
And she didn't wanna.
This is a first page. Of course I want to read more. It's vivid and funny and there's that nice "she didn't wanna" at the end.
You GOTTA have a hook that's not your first page though. Particularly if you're submitting to people on only want a cover letter, or only read email queries. Don't miss a chance to get theme to read your work by not having a good hook.
