“Hurry!” cried Frank.
Came the sounds of running footsteps from behind, loud cries and shouts.
Again Jack wrenched at the knob, and it came away in his fingers. Jack looked at the knob in dismay.
“It’s broken,” he cried.
At that moment the first Russian hove in sight. He saw the lads at the same moment Frank perceived him. Both raised their revolvers simultaneously, but Frank was the first to fire.
“Blow the lock off the door!” cried Frank. “I’ll hold ’em back.”
Jack placed the muzzle of his revolver to the lock and pulled the trigger. Still the door would not open.
A second Russian came into sight in the rear. Again Frank fired with excellent result.
“Open the door!” he cried to Jack.
“It won’t open,” Jack shouted back.
