Reynie answers to the ad in the newspaper that Miss Perumal showed him. The ad said "ARE YOU A GIFTED CHILD LOOKING FOR SPECIAL OPPORTUNITIES?" Reynie was the only one that passed in the first round.
How did HE get in?!
Reynie easily passes all of the tests and meets the other kids who passed with him. They also meet Mr. Benedict, the test creator, who tells them about the mission to go to Nomansan Island.
Kate, Constance, Sticky, and Reynie call themselves the Mysterious Benedict Society. They arrive at Nomansan Island. Sticky and Reynie make perfect scores on their tests, which made Martina Crowe jealous of them.
You losers will NEVER become Messengers!
What's up with HER?
The kids find out about the Whisperer and the Messengers that send the messages. Reynie and Sticky find a way for Kate and Constance to cheat on the tests so that they can be Messengers. Sticky gets caught cheating and gets sent to the Waiting Room.
OH, NOO! What's going to happen to me???
The Mysterious Benedict Society tries to sneak around the school to find out more about the Whisperer. Reynie and Sticky also become Messengers. They try to read Mr. Curtain's journal to see what he's planning, and the kids find out about his Sudden Amnesia Disease.
Kate tries to eavesdrop on Mr. Curtain, S.Q., and Martina through the drain. They hear a sound, and Mr. Curtain gets suspicious and flushes the drain with water. Kate got washed down the drain and fell into a body of water where she thought she saw a shark.
