Jude Watson

Jude Watson

Ekaterina Branch. Watson has written for years under the alias Judy Blundell. As Blundell, she won the National Book Award for What I Saw and How I Lied — a nod to her own double life. Could she be a Madrigal? Watson’s current headquarters are located in Katonah, New York.

Isabel Kabra trails Amy and Dan in Australia, where they are researching a little-known outlaw named Bob Troppo. They rejected Isabel’s offer of an alliance, and she is now determined to eliminate them from the competition. Permanently. Amy and Dan’s parents were murdered for the Clue hunt... and they may be left to face the same fate.
