"This way," directed the chief tersely.

Mr. Grimm walked along beside him. They skirted the end of the ball-room until they came to another door opening into the hall. Chief Campbell pushed it open, and entered. One of his men stood just inside.

"What was it, Gray?" asked the chief.

"Señor Alvarez, of the Mexican legation, was shot," was the reply.

"Dead?"

"Only wounded. He's in that room," and he indicated a door a little way down the hall. "Fairchild, two servants, and a physician are with him."

"Who shot him?"

"Don't know. We found him lying in the hall here."

Still followed by Mr. Grimm, the chief entered the room, and together they bent over the wounded man. The bullet had entered the torso just below the ribs on the left side.

"It's a clean wound," the physician was explaining. "The bullet passed through. There's no immediate danger."
