The key at last! It was larger than the others, which he judged were the handcuff keys. The padlock snapped and he unhooked the chain.
"That's that," he whispered, quietly. "Now for the handcuffs."
One by one the other boys presented their shackled wrists to him in the darkness and he groped for the key that would set them free. In a tense silence he fumbled with the locks and the handcuffs but, one by one, the handcuffs opened, one by one the boys moved quietly aside, rubbing their chafed wrists.
At last the task was finished. They were free again.
