We heard the sound of a shot and presently of slapping footsteps.
"Let me in," called a panting voice.
Alderson turned to me.
"It's Williams, sir. Shall I let him in?"
"Yes."
There came the crack of a rifle. Simultaneously Williams burst in on us.
"They're shooting at me, sir. I watched my chance to follow you."
"You're an honest man?" I asked sharply.
"Of course I am, sir. Couldn't say so with all of them around me."
"Good." I gave Jimmie the key of our armory. "Take Williams down and let him choose a revolver and a cutlas."
