Becky fell to the ground.
The cowboy, however, felt a sharp pain in his arm and doubled over. Clutching his arm, he heard the door swing close in automation.
The others were horror-stricken. They could not believe what they had just seen.

The arrows, they saw, were very sharp. Except for one of the sharp heads that cut across the skin of Andrew’s arm, the arrows shot through the air and struck the marble wall before dropping to the ground in a clatter.
