What lesson did you learn from the story?
Never take pompous people seriously and always expect everyone to do the unexpected. No one should be excluded from being a suspect.
Did anyone in the book do something you did not like?
The sculptor, but cannot state why. That would give the story away.
What was the problem in the book, and how was it solved?
Kevin wanting to know what is behind a locked door. He keeps asking his father and finally learns what he wants to know most.
