The Adventures of Tom Sawyer
How we cite our quotes:
[Injun Joe] had been careful to begin both of his inquest-statements with the fight, without confessing the grave-robbery that preceded it; therefore it was deemed wisest not to try the case in the courts at present. (11.36)
Injun Joe reveals himself to be just as skilled a manipulator as Tom – he can lie about a murder without slipping up or cracking under pressure. But Injun Joe's abilities are in no way admirable.
Then [Becky] sat moody, with wounded pride until the bell rang. She roused up, now, with a vindictive cast in her eye, and gave her plaited tails a shake and said she knew what she'd do. (18.78)
Even Becky, the picture of innocence, turns to manipulation when Tom ignores her – and she gets what she wants as a result. Tom, it must be remembered, does not have a monopoly on trickery.
"A thought shot like lightning through Tom's brain. He sprang to his feet and shouted –
"I done it!"
The school stared in perplexity at this incredible folly. Tom stood a moment, to gather his dismembered faculties; and when he stepped forward to go to his punishment the surprise, the gratitude, the adoration that shone upon him out of poor Becky's eyes seemed pay enough for a hundred floggings. (30.30-32)
Here, even as Tom sacrifices himself, the manipulative aspect of his actions should be acknowledged. He is putting himself on the line in order to help Becky, yes, but also to win her back.
