39 Clues Book 2- One False Note

Today I started reading the second book in the series 39 Clues. I did not know this but the 39 Clues Books are written by different authors. The first is written by Rick Riodan. The second is written by Gordon Korman. The third is written by Peter Larengis and is titled The Sword Thief. So far in book 2 Dan and Amy Cahill have gone into catacombs but not like spooky scary bone catacombs. More like narrow hallway maze catacombs. They eventually found their way out by following a light source. They did not know what it was at first but it lead them to a room with lots of drums. The tried to move a drum but they were stuck in place. They found a metal ladder blocking the way out. They heave-ho'ed and brought it down. On the other side there were lots of figures in black robes. Da dum daaaaaa. Cliffhanger!
