Answer the following question in 30-40 words.
Describe the curious episode which took place in a clergyman’s study.
A clergyman and his wife were awakened very early in the morning by noises coming from the study. They crept downstairs and heard the chink of money being taken from the clergyman’s desk. With a poker grasped firmly in his hand, the clergyman hoped to surprise the thief. However, it was he who was surprised when he found the room to be empty. He and his wife looked under the desk, behind the curtains, and even up the chimney. There was nobody there. Yet the desk had been opened and the housekeeping money was missing. It was a curious episode, and the clergyman kept saying the words “extraordinary affair” for the rest of the day.
