Shep lives in Australia. He is a bush pilot. He is also a surfer and does not know about the 39 Clues unlike his cousin Arthur. However, his cousin Arthur was close with the Vespers. Therefore, Shep might be close with them, too. He could have lied to Amy and Dan when they visited. Growing up, he was close friends with Arthur, or "Artie" as he called him. Shep did not get the letter about Arthur and Hope's funeral until the day of the funeral which he was very depressed about.

Appearance and Personality
He loves surfing and wishes he was a better uncle to Dan and Amy. When he finds them with their au pair on his door step, he seems really surprised. His house is really messy because he's a self admitted pack-rat.Dan wishes that he could have been their official guardian, instead of Beatrice Cahill. He is the cousin of Arthur Trent and is probably a Vesper, although he has little to no interest in the Clues.
Dan never gave the truth until later, when the truth is told, Shep Trent had not believed it. Last seen when Amy and Dan flew to Indonesia. He was supposed to fly them there, but Irina got rid of him and made him get arrested by posing as the grandmother of Dan and Amy.
