Amy and dan!

The Aloe Clue and that they were Madrigals
It would ruin the books if told you all. Dan and Amy only find 10 of the 39 clues and the big 39th clue. Here are some: Book 1: A Visle Book 2: tungsten Book 3: gold book 4: myrh book 5: amber book 6: The clue they fnd is water but Irina Spasksy kew of anohter clue being a rosemary Book 7: Aloe and the Tomas clue is diamond book 10: there is a clue that i will not say but the 39th clue they find is a serum to make you all 5 branches. Each of the 38 clues is an ingredent to the serum. Look, This is helpful, but wrong. I know they find all of them. I've only read up to seven, wroking on eight, but still, It would ruin the series if they don't find them all. Sor-ry! :'( Just saying.
Amy Cahill hid a clue in her arm in "The 39 Clues" series. She had a small microchip implanted under her skin which contained a vital clue to the location of the 39 Clues treasure.
