Read it to my 6 and 8 year old boys. I liked it more than them

This is the best book ever that I have read so far .

So cool and advent

Was very fun to read, kept me guessing about what happened next. Could use some modern day touches, but it was written in the 20s.

Just seeing this and reading the synopsis is a trip back to my childhood when I would devour all of these books . I will slowly purchase all of them. My parents bought me Hesse books but I foolishly traded them in for others I was more interested in . Little realizing how much I'd miss them down the road.

This was the best book I've Ever read even though I don't like mysteries I like these.Now I'll probably read the whole series.

I have all books in Hardback (HB). Yet the series started and became 65/6 books. You do not have 59-66. I want to download all to have them ditgitally. You are missing a boatload of Nancy Drew Original Series as well. Visit Wikipedia and there is a list of ALL books from both series.

There is a huge mystery and then it becomes more than one mystery

Very compelling book. A real page turner.

The tower treasure is one of the best mysteries I ever read
