Ivy and Bean No News Is Good News (Book 8) by Annie Barrows
Ivy and Bean need some money. Ten dollars, to be exact. Never mind what for. Okay, it's for low-fat Belldeloon cheese in a special just-for you serving size. Don't ask why. How are Ivy and Bean going to make ten dollars? Hey, maybe they should write a newspaper about Pancake Court and sell it! Great idea! And easy, too. All they have to do is snoop around the neighborhood. Wow... It's very interesting what they can find out. It's even more interesting when the neighbors read about it inthe newspaper.
