By Wednesday afternoon they were not so happy. A second letter arrived for them -- from O. G.

Why don't you listen to me? I am getting angry. Leave Box 5 free for me. And where are my 20,000 francs? On Friday Daaé must sing Margarita again. She is now the best singer in Paris. La Carlotta cannot sing -- she has a very ugly voice, like a toad.

That was Tuesday night. On Wednesday morning Monsieur Armand and Monsieur Firmin were happy men. Paris liked the new Margarita -- everything in life was good. The next opera night was Friday. It was Faust again, but this time with La Carlotta singing Margarita.

"So, Firmin, is this still a joke?" Monsieur Armand shouted. "What are we going to do now, eh? Is O. G. the director here, or are we?"

Remember, I am a bad enemy. O. G.

"Don't shout, Armand," said Monsieur Firmin tiredly. "I don't know the answers. Let's talk to Madame Giry, the doorkeeper of Box 5. Perhaps she can help us."

But Madame Giry was not helpful. Madame Giry was not afraid of ghosts, and she was not afraid of directors of Opera Houses.

"And some people say he has no body," said Monsieur Firmin. "What do you say, Madame Giry?"

"People say that you're a friend of the Opera ghost, Madame Giry," Monsieur Armand began. "Tell us about him. Some people say he has no head."

"Because, Monsieur, the Opera ghost is angry with you. When the ghost wants something, he must have it. He is clever and dangerous, this ghost. The old directors before you, they knew that, oh yes. At first they tried to stop him. Then there were many accidents in the Opera House, many strange accidents. And when did these accidents happen? When the ghost was angry! So, the old directors learnt very quickly. The ghost wants Box 5? He can have it every night. The ghost wants money? Let's give the money to him at once. Oh yes, the old directors understood very well."

"What!" Monsieur Armand shouted. He stood up, and his face was red and angry. "Listen to me, woman --"

Madame Giry looked at the two men and laughed. "I say that the directors of the Opera House are fools!"

"Oh, sit down, Armand, and listen," said Monsieur Firmin. "Why do you say that, Madame Giry?"

"Well, we can try that, Armand. But we don't want any accidents."

"But we are the directors, not the Opera ghost!" Monsieur Armand shouted. He turned to Monsieur Firmin. "This woman is mad. Why do we listen to her? On Friday night La Carlotta is going to sing Margarita. And you and I, Firmin, are going to watch the opera from Box 5."

Madame Giry came nearer to the two men. "Listen to me," she said quietly. "Remember Joseph Buquet? I tell you, the Opera ghost is a good friend, but a bad enemy."

The two men stared at her. "Those words," Monsieur Firmin said slowly, "why did you say those words, Madame Giry?"

"Because the ghost says them to me. I never see him, but I often hear him. He has a very nice voice -- and he doesn't shout at people."
