The Whisperer is an invention of Ledroptha Curtain to assist in his goal of dominating the world.
Appearance and usesEdit
It is (originally) like two chairs, with helmets making them look like old-fashioned hair dryers. One chair has a red helmet, which automatically lowers onto Curtain's head when he sits in the chair but refuses to lower for anyone else, and which can transmit his thoughts to whoever sits in the other chair. He often uses this to brainsweep them, taking away some or all of their memories so that they will trust him. In the days of the Institute, he would use students (Messengers) to transmit the thoughts he told them to think (propaganda such as, "dare not defy the Institute") to every television, cell phone, and radio in the world, so that those using them would believe him as well.
By the end of The Mysterious Benedict Society, the Whisperer is in the hands of Mr. Benedict, who can use it because his brain is similar enough to that of his twin brother Curtain to fool the Whisperer. He uses it to reverse the brainsweeps (and uncover memories that were lost without brainsweeps, such as Constance Contraire's), and nearly finds a way to cure narcolepsy with it.
In The Mysterious Benedict Society and the Prisoner's Dilemma, Curtain takes back the Whisperer and makes it portable: it is now one wheelchair (with a helmet), and he can brainsweep others from a distance simply by concentrating on them. But it turns out that Mr. Benedict, guessing that it would be stolen, had programmed it to malfunction, and so Curtain is unable to use it. When he jumps out and stops controlling it, it wheels wildly by itself and crashes into a crane, destroying itself.
