In Tom Sawyer, how does Huck inadvertently inform the Welshman of the true identity of the "deaf and dumb" Spaniard?
As Huck Finn is describing the intruders to the Welshman, he makes the mistake of describing the speech of the deaf and mute Spaniard. The Welshman realizes now that Huck knows more than he is letting on. The older man reassures Huck of his safety, and Huck whispers the true name of the Spaniard in the Welshman's ear.
"'Taint a Spaniard - it's Injun Joe!"
