John and May were quite rich. They had a big, beautiful house full of expensive paintings. One day, they got an envelope with two tickets inside.
They had many friends and were surprised, however, when they could not find out who had sent them the tickets. There was no letter in the envelope with two tickets. "They've forgotten to put a letter in it." John said, "How strange! We don't know whom to thank. "They phoned many of their friends and asked, "Did you send us theatre tickets?" "No," their friends said. "We didn't send them." "It's strange,'' May told her husband, "but we won't waste the tickets. Everyone says that the play is very good."
So they went to the theatre. They didn't really enjoy the play, because they were worrying all the time. The play started at eight o'clock and finished at ten. When they got home, it was after eleven.
There was a note on their front door. It said, "We hope you enjoyed the play." Inside the house there was no painting left. They had all been stolen.
