Ian Kabra is a Lucian operative who, with his sister Natalie, makes up one of the first teams in the Clue Hunt. His family were the leaders of the Lucian Branch. He was fourteen years old in the original Series 1, but is sixteen years-old in Series 2, both times the same age as Amy Cahill. Ian is described in the 39 Clues books as being extremely good-looking. He has tan skin, amber eyes, and silky black hair. He has a British accent and dresses in fine clothing, notably Armani, Prada, and Ralph Lauren suits and other designer wear. He often acts older than his current age, but sometimes he can be immature. Ian Kabra is Natalie Kabra's older brother, and presumes he is also in charge of her. Despite his snobbish attitude, he knows how the world once saw him and actively makes attempts to change this in the later books. He always tried to please his mother, until he realized what kind of a person his mother was.



Midnight Ride

On Christmas Eve 2007, Isabel Kabra sent Ian and Natalie Kabra to steal the snowglobe with Paul Revere's engagement ring in Grace's mansion during her annual Christmas party. However, they fail and are foiled unintentionally by Amy and Dan Cahill.

Sometime before Grace's funeral, Ian was briefed about the impending Clue Hunt by his mother, and warned about the threat posed by Amy and Dan.

The Maze of Bones

In Ian's first appearance at Grace Cahill's funeral, he and Natalie walk towards Dan and Amy. Dan sees them and says that 'the cobras' (Amy and Dan's nickname for them) are coming their way. Amy curses herself for noticing how handsome Ian is. Ian and Natalie accept the hunt for Clues. Later, in the catacombs, Ian was on the hunt of a Clue with his sister. They attempted to knock out Amy and Dan with a dart gun, but Alistair Oh tackled them, giving the Cahill siblings enough time to escape. Later, Ian tricked Amy into thinking that he poisoned her brother Dan and that only he has the antidote. Amy gave him the lead with the hope of getting the "antidote" and Ian escaped. Ian hadn't really poisoned him but it is unknown what the 'antidote that he gave Amy actually was.


One False Note

Ian and Natalie captured Amy and Dan on their yacht in Venice and tried to get their lead. When they realized that the Cahills did not have the lead with them, the Kabras attempted to dispose of the Cahill siblings. Later, he and Natalie hold Dan and Amy hostage in Fidelio Racco's house. Ian played a certain piece composed by Mozart, thinking that it will lead him to the Clue since they found out that Amy and Dan looked it up and figured out the clue through the Internet. The piece that the Kabras received, however, was different from the genuine one that the Cahills had. It contained a false note designed to trigger a bomb in the harpsichord. The harpsichord on which Ian played the piece exploded because of the bomb, and the Kabras were rendered unconscious.

The Sword Thief

Ian suggested that he and his sister, Natalie, form an alliance with Amy, Dan, and Alistair Oh. They accept, and the five worked together, tracing the clues to a man named Toyotomi Hideyoshi. Throughout the alliance, Ian and Amy appeared to be falling for one another, but that ends when he and Natalie betray Amy and Dan by leaving them in a cave, after Dan falsely told them that the lead pointed to Lake Tash, in Kyrgyzstan, when they should have gone to Egypt, which is why they were later absent from Book 4. This reference also appears in Mission 4. Afterwards, Amy had a hard time forgetting Ian, and there are hints that he appears to have genuine affection for her.

Mission 4: The Lucian Fort

In this mission, Ian and Natalie Kabra went to Kyrgyzstan to find the supposed "Clue" in Lake Tash. They rented a hotel in Bishkek, the capital of Kyrgyzstan. The bellboy called them "terrible children" when later inquired. In their hotel room, they had written "Flight to Budapest" and than later erased it. In Mission Four, you get to meet Ian and Natalie. In the mission, Ian said he wanted to see the Crown of St. Stephen. When you ask him why, he says, "Oh, um, nothing. It's just, um . . . very old. Too old, actually. It's probably covered in . . . crown germs. In fact, I probably won't go see it at all." He also revealed they are monitoring the area when talking.

(In the same paper that they wrote "Flight to Budapest", you can see in the corner "Ian+Amy" inside a heart, which later was crossed out)

The Black Circle

Ian makes multiple appearances in this book, including a time where he attempts to "reconcile" with Amy and Dan, only to be kicked in the shin by Amy. He also competes with the Holts and Amy and Dan (who are in alliance at this point) and loses leads to them, several times.

In Too Deep

Ian Kabra was on the boat when Isabel threatened to feed Amy to the sharks.

The Viper's Nest

When Ian and Isabel are in the airport, Ian says, "They're asking for it, Heaven forbid they listen to the brains of the outfit..." "And that would be?" Isabel said. "Well, the sister, Amy..." "He felt a smile creeping upon his face" is what the book says, then his mother asks him about it and he says he blushes. In addition, Ian was very concerned about the green liquid he snatched from Amy and Dan in the first book. He was nervous when his mother wanted to give it to Amy and Dan.

The Emperor's Code

Ian and Natalie kidnaps Dan and grills him for information. Then he is seen climbing up Mount Everest on a pack of Sherpa. Ian nearly falls of the mountain, but Amy saves him, sacrificing the Janus serum for him.

Storm Warning

Dan, Amy, and Nellie plan a scheme to get a wolf fang charm from Isabel, which they believe may be important to the hunt. Dan traps Ian Kabra, as Amy and Nellie manage to get Isabel unconscious and retrieve the fang. Later, Ian helps Isabel and Natalie chase Dan, Amy, Nellie, and Lester.

At some point before the events of Into the Gauntlet, Ian travels to Cambodia alone in search of a rumored Clue hidden in Angkor Wat. He is attacked by, and defeats, Vesper agents (whom he believes to be Madrigals), but leaves without finding the Clue.

Into the Gauntlet

Just like the other competitors, he also gave his clues to save his loved ones. Earlier on, he discovered that Hope and Arthur Trent were murdered by his mom (Isabel Kabra.).

The Black Book of Buried Secrets

In The Black Book of Buried Secrets it is said that Ian took over his parents' art business. Ian and Natalie also witnessed Isabel's court case where she pleaded guilty. With Vikram and the other major Lucian leaders in hiding, it is possible that Ian, along with his sister Natalie, may become the new leaders of the Lucian branch.

Evan had overreacted at his presence and had grabbed a ping-pong paddle. Ian accused him of playing a game. He finally ended up having to feed Saladin red snapper on page 63, chapter 11. Amy strongly believes Vesper Three is Ian. Ian calls Amy in response to this. Amy ends the call, furious that Ian would betray Natalie. These suspicions were planted by Sinead Starling, who was the real Vesper Three. Sinead falsely told Amy that Ian was a Vesper Three suspect in order to attract attention away from herself. Amy says that she hates Ian.

In the beginning of the Clue Hunt, Ian is ruthless and does everything he can to win. But after he and his sister make an alliance with the Cahill siblings in The Sword Thief, he starts paying attention to Amy and finds himself saving her life in the entrance to the hidden cave. After that, though, he abandons Alistair and the siblings in the cave and he leaves, trapping them inside. In the next books, he starts hesitating a little when he has to do something bad to Amy, like when he didn't help his mother throw Amy to the sharks in In Too Deep. After Amy saves him in the top of the Everest mountain in The Emperor's Code, he is shown feeling even guilty. In Into the Gauntlet, he is very sad that his mother is never satisfied with him and Natalie, so he breaks into their parents' secret library, finding out that his mother murdered Amy and Dan's parents and worrying if Amy and Dan know about it. In the end of the novel, he and his sister decide to stop being "bad" and try to change. During the Doublecross series, Ian starts to fall for Cara Pierce and tries his best to make her smile and impress her.
