A King's Ransom

Cheyenne distracts Jonah and Hamilton while Casper traps the Cahills who just found the map with a knife. Cheyenne and Casper later pursue the Cahills to the library Katja Mavel works at. Cheyenne holds Atticus although Jake tries to stop her. Cheyenne, along with her brother lock Dan and Amy in a sealed room where they are in danger of losing oxygen. Cheyenne and Casper flee after Dan and Amy escape.


Cheyenne and her brother stole "The Book of Ingenious Devices" from the Pergamon Museum while Amy and Dan are trying to steal the Golden Jubilee Diamond. Later she and Casper follow Amy and Dan to Timbuktu to find the "Apology".She then gives a clue to Amy by saying"Remember this and then there were six",meaning that there are only six hostages and one of them is already dead.

Cheyenne's message

However, Sandy Bancroft, pretending to be asleep, sends a voice note to Vesper One. Vesper One then has Casper and Cheyenne locked in a room with water tied to a pole, but Amy and Dan save them. After the Machina Fini Mundi is destroyed, Cheyenne is arrested with Casper and Sandy Bancroft.
