Phantom- Box Number 5

  “They must have been dining, sir, and seemed more inclined to lark about than to listen to good music. The moment they entered the box, they came out again and called the box-keeper, who asked them what they wanted. They said, ‘Look in the box: there’s no one there, is there?’ ‘No,’ said the woman. ‘Well,’ said they, ‘when we went in, we heard a voice saying that the box was taken!’”
…
  “However, when the people arrived,” roared Richard, “there was no one in the box, was there?”
  “Not a soul, sir, not a soul! Nor in the box on the right, nor in the box on the left: not a soul, sir, I swear! The box-keeper told it me often enough, which proves that it was all a joke.”
