Hidden in a deep underground bunker, the Wyomings demand that Atticus give them all the information he knows about being a Guardian. In an effort to stall, Atticus claims that he only knows the encryption code for access to the information they want, which is hidden on his flash drive, and that it will take time to decode it.

From Quiz How Much Do Really Know About "The 39 Clues"?

11. What is one thing that makes people know that Amy and Dan are brother and sister?

Answer: Evan Tolliver

It has been two years since the Clue hunt had finished, and Dan and Amy have been trying to move on with their lives. Fiske Cahill and Nellie Gomez have joint custody of the kids, and they are wealthy beyond their dreams. Before their adventures, Amy would not have dreamed of approaching Evan, whom she had had a crush on for some time. Her experiences, however, had given her a new confidence in herself. Amy describes Evan Tolliver in her thoughts as "the Bill Gates of Attleboro Junior/Senior High, ... assigned him the nickname Adorkable."

13. Who is Lord Vesper's spy in the Cahill household who tells him of the completion of the serum?

From Quiz "The 39 Clues" Book 11: "Vespers Rising"

Answer: Maria (the housekeeper)

Maria had spied on the Cahills for Lord Vesper for years, and she informed him of the change that had come over Gideon: "He's made something in that evil laboratory of his, m'lord. Sick for a while, he was. But now he's changed - turned stronger, quicker, even his hearing is uncanny! I heard him talking to himself about a formula, a concoction. He's taken to witchcraft, I fear. M'lord, it's not natural, the things I seen him do!"

14. Every Cahill branch now knows the location of one of the Madrigal strongholds: the Cahill ancestral home in the Irish Sea. Where is the other Madrigal stronghold, an island known for its large stone-head statues?

From Quiz The 39 Clues: The Black Book of Buried Secrets

Answer: Easter Island & Rapa Nui & Isla de Pascua

With its remoteness from pretty much anywhere else in the world, it made an excellent stronghold for Madrigal agents. It was unlikely to be accidentally discovered by any of the other Cahill branches. In the middle of the 20th century, the Madrigals constructed a fake moie (stone-head statue) on this Polynesian island to hide the entrance to their underground stronghold. With state-of-the-art technology, the Madrigals are able to keep close tabs on Cahill activity all around the globe from this location.

15. Shortly after arriving in Sydney, while traveling on a bus from the airport, Amy has something stolen from her. What is it?

Answer: Her grandmother's necklace

A 'sweet' elderly woman sits behind Amy and Dan on the bus, and continually 'accidentally' hits the back of Amy's head with a map. Amy realizes it quickly, but not before the old woman gets off the bus. Shortly afterwards, Amy encounters Isabel Kabra - the mother of Ian and Natalie, in the Justice and Police Museum. Who do you suppose stole the necklace?

16. Dan and Amy meet a young man named Theo Cotter in the bazaar, who helps them dodge a poor bargain, avoid Irina Spasky, and find a museum. While in the Sennari House museum, Amy spots a tile with this Cahill branch crest on it.

From Quiz "The 39 Clues" Book 4: "Beyond the Grave"

Answer: Lucian

Early indications are that Napoleon is linked to the current Clue that Amy and Dan are looking for. Behind that tile Dan finds a leather tube with a small bit of rolled parchment inside. It reads: "et pour la plus grand gloire des descendants de Luc et mon Empereur, l'indice est maintenant en route pour le Palais du La Paris. - B.D. 1821"

17. The plane that Dan and Amy take from Italy doesn't fly directly to Japan. Instead, it lands for a refueling layover in which city?

From Quiz "The 39 Clues" Book 3: "The Sword Thief"

Answer: Moscow, Russia.

Alistair attempts to throw off Irina Spasky from their trail, but she manages to keep track of Alistair and the Cahill kids through the GPS units in their phones.

18. Who begins a hunger strike while traveling on the train?

From Quiz "The 39 Clues" Book 2: "One False Note"

While in the security room, Herr Rommel shows Atticus the state-of-the-art facial recognition program, and Atticus tries to keep anyone from noticing the two Cahill kids. He also sees Interpol agent Milos Vanek trailing Dan through the museum. Unfortunately, Amy sets off the metal detector, ruining whatever chance they have, and Atticus uses his computer skills to shut down the power. Dan and Jake get out, but Amy and Atticus both get caught.

21. Irina Spasky had a son that died. What was his name?

From Quiz The 39 Clues

Answer: Nikolai

Nikolai, Irina's son, died while she was in a mission that Isabel Kabra sent her to. Isabel did not allow Irina contact with her sick son.

22. In the book "Vespers Rising", the four oldest children of Gideon and Olivia got to taste the serum Gideon made. Due to the serum they each developed a personality. What personality did Jane develop?

From Quiz The Cahills

Answer: devotion to every kind of art

The serum of Gideon made Luke cunning, with a passion for poison and stealthiness. Katherine got supreme knowledge. Thomas got amazing physical strength. Jane was devoted to every kind of art. Because Madeline was not actually born at the time the serum got created, she never got a portion and was therefore normal.

23. Which branch's symbol is the dragon?

From Quiz How Much Do Really Know About "The 39 Clues"?

25. En route to their first destination, Amy and Dan discover that the girl that helped them get on the train unnoticed by the police is in fact a Vesper agent! On the train she pretended to be Vanessa Mallory; what is her real name?

From Quiz "Cahills vs Vespers" Book 2: "A King's Ransom"

Answer: Cheyenne Wyoming

Cheyenne Wyoming is the twin sister of Casper, who Dan and Amy had already encountered. They also learned through a message from Ian and Sinead back at their HQ in the United States that Cheyenne was part of the Vesper inner circle, specifically 'Vesper Six'. Along with this little tidbit of information, Dan and Amy learned that Casper, whom they they thought had died, was still alive!

26. In an update on Madrigal member activities, information is revealed about Dan and Amy's activities at school after the end of the Clue Hunt. For what was Dan NOT sent to the office on his first day back at school?

From Quiz The 39 Clues: The Black Book of Buried Secrets

Answer: Assaulting his English teacher, Miss Bradford.

When Mr. Garcia asked why he had missed the first three weeks of school, Dan replied, "It's top secret. If I told you, someone in my family might try to kill you. But I'd stop them. I learned wushu from Shaolin monks!" Then he tried to demonstrate. When given the task of writing an essay on Benjamin Franklin in history class, Dan asked his teacher if he could write about Franklin's interest in farts. When Mrs. Travis told him that he was "disrespecting on of our most revered founders," Dan grew angry that she was ignoring his greatest accomplishment. In music class, when Mr. Haverford explained that Mozart had died bankrupt, Dan was quick to point out that it was because he'd spent all his money "importing crazy materials from around the world, like tungsten." He then tried to prove it by pulling one of the samurai swords he'd found on the hunt, waving it around.

27. Amy finds a brochure describing the Jolly Codger Pirate's Cove tour, where tourists visit a number of islands known to have been frequented by famous pirates. What name catches Amy's attention as a known associate of Anne Bonny's?

Answer: Jack Rackham

Jack Rackham was an English Pirate known as "Calico Jack" and he lived 1682 until 1720. He earned his name from the calico clothing that he wore. Calico is a plain-woven textile made from unbleached, and often not fully processed, cotton.

28. While conducting research at the library in the 'Mozarthaus,' Amy discovers information about Maria Anna "Nannerl" Mozart. What was her relationship to W.A. Mozart?

From Quiz "The 39 Clues" Book 2: "One False Note"

Answer: Older sister

Maria Anna "Nannerl" Mozart was, according to Amy's memories of conversations with Grace Cahill, just as talented as her younger brother, but due to her gender, never had the same training or opportunities as Wolfgang.
