I believe the title of the book I am looking to find is called “Money”
It’s about several children who find hidden money in an old man’s house and agree to keep it a secret, so they can not use any of it.
One of the boys is obsessed with getting candy, another wants to invest in stocks and bonds…definitely a girl in this group, however I can’t remember who it was she wanted to buy.
If you can help identify the book I would be delighted. The title always brings up millions of response in search engine and of course, the first few hundred are Martin Amis “Money” — however, that story is very different than the book I seek.
