Swamped

At your age, your throwing arm isn't what it used to be. But it's not so hard to aim low.

You grab a moderately large fish, and fling it at the man's legs. He falls over. Now nobody's standing up. Which means you have time to pull another scare tactic. You spot a cauldron on top of a pile of wood, and make a run for it. This must be the mixture they were talking about.

"Stay back or I burn this," you say calmly as they all start getting up.

"We got masks," says the most defiant one. He still doesn't seem very worried. "And if the best you got is flinging a fish at me, then..."

He doesn't finish, because he's interrupted by another fish striking him in the back of the head. He falls over.

You look towards the front door, and see that the others have been similarly immobilized, and Black is dragging an unconscious man in.

"See if you can find some nets or something to tie them up with," he says calmly. "I have to get the other one, just barely caught her when she opened the door. When I get back, we'll bring Sunflower in."

Right. This is a fishmonger's, nets seem fairly likely to be around somewhere. You do some searching and find a few, and toss them over the unconscious strangers. With one more for the other one Black's supposed to be bringing along.

You don't recognize any of them. No idea if they're locals or from out of town. But you do notice something distinctive about one of them.
