Rumpole moved fast. With her left hand she reached beneath the hair at the back of her head and pulled out a large spoked wheel with rimmed edges.

“Where were you hiding that?” Neptune asked in disbelief.

With her right hand, she pulled on the golden cord that bound her hair. The hair fell loose, fanning out behind her, and the cord wrapped itself around the edge of the wheel, which spun in her hand and drew it in. Then she drew her left hand back and tossed the wheel like a discus toward them while holding on to the cord.

The spinning wheel zoomed toward Neptune, Yatsuhashi, and Fox. Then it wrapped the cord around the trio, binding them together, arms pressed tightly to their sides.

“You were saying?” Rumpole said.

Yatsuhashi grunted and strained at their bindings, tightening them even more.

Neptune gasped. “Yatsuhashi! Stop! Can’t breathe.”

“What just happened?” Fox sent.

“She’s been carrying some kind of wheel on her back,” Neptune returned. “And she wrapped a cord around it, then spun it toward us, tying us up.”

“I can’t believe she’s been carrying that thing around all this time,” Yatsuhashi sent.

Rumpole’s wheel returned to her. “I’m disappointed. If this is the best you can do, then maybe we should expel you. You certainly don’t belong here.”

Fox was cheerful, since he knew the way out. He flicked his wrists and the binding came loose at once. “Arm blades for the win,” he said. “Nice try, Professor!” He ran toward her, and she fled.
