Butler- Dart Rifle Shooting

The two guards at the door were actually growling at anyone who ventured too close. They were big, even for humans, and Holly was glad that no fine motor skill would be called for. Two quick jabs into the nerve cluster above the knee should be plenty to bring these guys down.

Simple, thought Holly, then: I shouldn’t have thought that. Whenever you think that, something goes wrong.

Of course she was dead right.

Someone started firing on Kronski’s guards. Silver darts streaked through the air, then punctured skin with a sickening thunk.

Holly knew instinctively who the shooter was, and her suspicions were confirmed when she spotted a familiar silhouette anchored in the roof beams.

Butler!

The bodyguard was draped in a desert blanket, but Holly identified him from the shape of his head and also from his unmistakable shooting position: left elbow cocked out a little more than most marksmen preferred.

Young Artemis sent him back to clear a path for us, she realized. Or maybe Butler made the decision himself.

Whichever it was, Butler was not helping as much as he’d hoped.

With the guards dropping, the Extinctionists were piling over their fallen captors, desperate to be free of this building.

Caged Extinctionists, thought Holly. I’m sure Artemis appreciates that irony.

Just as Holly drew back her fists, the two guards at the kitchen door clutched their necks and pitched forward, unconscious before they hit the floor.

Nice shooting. Two shots in under a second from eighty yards out. With darts too, which are about as accurate as wet sponges.
...

Butler ducked into a dark corner and quickly broke down his dart rifle into almost a dozen parts, slotting them into various garbage bins. It was possible that he could slip the Fez Saïss Airport customs men some baksheesh and simply stow the weapon under his seat, but these days it was better to be safe than sorry.
