The Voice in the Dark Room

“Are you the new recruit?” asked a heavy voice.
And in some strange way, though there was not the shadow of a shape in the gloom, Syme knew two things: first, that it came from a man of massive stature; and second, that the man had his back to him.
“Are you the new recruit?” said the invisible chief, who seemed to have heard all about it. “All right. You are engaged.”
Syme, quite swept off his feet, made a feeble fight against this irrevocable phrase.
“I really have no experience,” he began.
“No one has any experience,” said the other, “of the Battle of Armageddon.”
“But I am really unfit--”
“You are willing, that is enough,” said the unknown.
“Well, really,” said Syme, “I don't know of any profession of which mere willingness is the final test.”
“I do,” said the other--“martyrs. I am condemning you to death. Good-day.”
