The wytches looked pleased. They conferred with an officer, who started barking orders. One of the Khalidorans raised a torch and waved it twice. Lefty and Bernerd took torches of their own, walked to either side of the bridge, and waved twice.

All clear. Right.

Kylar drew Retribution. As it hissed out of the scabbard, the bashers turned. Lefty blinked and leaned forward. With the torches in their hands blotting out their night vision, all they saw was a thin strip of dark metal bobbing and floating through the air. Then it moved with terrible speed.

In a moment, both men were dead. Kylar replaced the torch he’d plucked from Bernerd’s hand and checked the men on the barges. They had already formed up and were walking, single-file, up the narrow switchbacks that led to the bridge.

Grabbing the keys off Bernerd’s body, Kylar opened the gate and slipped through the inset door. The crank and the release for the river gate were there. The gate itself was simply a massive, counterweighted portcullis that could drop into the water. In this case, onto a ship.

Kylar threw the release. The river gate dropped two feet—and didn’t crunch. It clanged. Kylar looked over the side of the bridge. The river gate had slammed down onto magical stops that glowed and sparked in the darkness. Wytches were on the deck of the first barge, shouting.

He ran into the guard station. There was a fire pit with a cauldron full of stew, cooking paraphernalia, a helmet, several cloaks, chests for the men’s personal belongings, and a set of knucklebones on the low table. There was a closet full of old broad carpets stuffed in fat buckets.

Kylar rushed out of the guard station. Surely the king wouldn’t have left his military bridge with only that defense. The pilings of the bridge were wood sheathed in iron—impervious to fire. The sheathed wood still got wet, but couldn’t breathe and release the water it absorbed, so every beam rotted within years and had to be replaced.

Why would the king be so particular about fire?

And then Kylar saw why. Along either side of the bridge were long wooden beams set on pivots. On the end of each beam was a huge clay globe as wide as Kylar was tall. At least part of the clay was molded over iron because a mooring rope was tied to an iron loop at the top of the globe. Several small handles also protruded from the sides.

Pulling on one handle, Kylar found a bracket. As he slid it out, a wash of oil fumes swept over his face.

It took him several precious seconds of staring at the entire contraption to understand. The arms would swing out over the side of the bridge, holding the globes full of oil, then drop them onto any boat passing underneath—and hopefully set it on fire in spectacular fashion.
