Amy and Dan Cahill never knew their parents. They passed away in a fire when the siblings were young and their stingy grandaunt Beatrice became their guardian. However, on the weekends, Amy and Dan stayed with their grandmother, Grace Cahill, whose adventurous life gave her great stories to entertain her grandchildren with. When Grace passes away, many relatives gather at the reading of her will. Amy and Dan learn that they are part of the Cahill Family: an ancient family with four (secretly five) branches: the Lucians, Janus, Tomas, and Ekaterinas, and secretly, the Madrigals. The founders of the Cahills, Gideon and Olivia Cahill had discovered a secret so powerful, that whoever found it would become the most powerful person in the entire world. In order to find the great secret, the searcher must have 39 different Clues, or ingredients, hidden throughout the world. When Grace died and her will was read, selectively chosen relatives had to make a choice: accept $1,000,000 or take the first Clue and start the hunt. Numerous relatives leave with the million dollars, including Aunt Beatrice, but seven teams stay:
- The Holt Family
- Irina Spasky
- Ian Kabra, Natalie Kabra
- The Starling Family
- Alistair Oh
- Jonah Wizard
- Amy and Dan Cahill
Although the "official" Clue-Hunt began at Grace's funeral, the competition has been going on since the separation of the original Cahill Family and the creation of the branches.
Members of the Cahill Family are sorted into their branches by their blood and their talents.
The Cahill Family is made up of four (secretly five) separate branches, always determined enemies of each other. Each branch has it's qualities and enhanced abilities, as found out when the Master Serum is discovered.
The Lucian Branch was founded by Luke Cahill.
Its qualities are ruthlessness tactics, strategy, spying, sabotage, and being secretive and shadowy. The best leaders and spies came from this branch. Isabel and Vikram Kabra were the leaders of this branch until Isabel went to jail and Vikram went in hiding with other top Lucians in London.
The Ekaterina Branch was founded by Katherine Cahill.
Its qualities are inventiveness, intellect, abstract
thinking, and overall smarts. The inventors, great thinkers, engineers, and archaeologists as well as many others came from this branch. Bae Oh was the leader of this branch until he was arrested for murder. Alistair Oh was the leader up to Trust No One. The current leader is Patricia Oh.
The Tomas Branch was founded by Thomas Cahill.
Its qualities are physical endurance and strength,
prowess, brawn, adventurousness, and determination. The best athletes, explorers, warriors, etc. came from this branch. Magnus Hansen is the current leader of this branch.
The Janus Branch was founded by Jane Cahill.
Its qualities are categorized into one world-art. The Janus
excel with many artistic things, whether it's painting a picture or breaking into a stronghold. The best artists, writers, singers, etc. came from this branch. Cora Wizard is the current leader of this branch.
The Madrigal Branch was founded by Madeleine Cahill.
Its qualities come from the heart and soul of a person, and
they tend to be humanitarians, peace-makers, etc., but also are sneaky, shadowy, smart, etc. This is because the goal of this branch is not to collect all 39 Clues, but to bring the family back together. Unfortunately, this oftentimes comes to the actions of killing, stealing, and destroying. Fiske Cahill is the current leader this branch, and Grace Cahill and William McIntyre were before they died. It is expected that Amy and Dan will take over for Fiske when he dies.
