What is the summary of The Adventures of Tom Sawyer?

Mark Twain's classic 19th century novel tells the story of
Tom Sawyer, a wild young boy who grows up on the Mississippi River. The story is
interconnected by a series of chapter "vignettes," usually highly dramatic and of a
comic nature. One of the most famous is the whitewashing scene where Tom convinces some
friends by the use of reverse psychology to paint his fence--for a price. Tom not only
gets out of the work he hates, but earns trade items from his gullible friends. Tom
falls for Becky Thatcher, the daughter of a local judge. Tom's best friend is the even
more untamed Huckleberry Finn; while hanging out in the cemetery one night, they witness
Injun Joe stab and kill the local doctor. The boys swear not to reveal what they have
seen, but when an innocent man is accused, Tom's and Huck's consciences get the best of
them. After the boys take a lengthy raft trip down the river pretending to be
pirates--and are later believed drowned by the town--the boys return home just in time
to see their own funerals. They eventually decide to testify in court, naming Injun Joe
as the killer, who escapes the courtroom.

While looking for
gold in an abandoned, haunted house, the hidden boys discover the disguised Injun Joe,
who is burying some stolen money. In doing so, Joe finds another treasure of gold. Joe
takes the money to hide it elsewhere; Tom and Huck decide to keep an eye on Joe in the
hope of discovering where he hides the treasure. Later, Tom and Becky take in a picnic
and decide to explore some caves, in which they get lost. Inside, they see Injun Joe,
but Tom and Becky manage to elude him and eventually escape. When Tom and Huck hear
later that the cave entrances have been sealed, they realize that Injun Joe must have
been left inside--possibly with the hidden treasure. When Tom and Huck return to search
the caves, they find the treasure. They become local heroes and the richest boys in
town. Huck, however, cannot stand the thought of being civilized, and he decides to
escape back to his old ways--setting the stage for Twain's classic followup novel,
The Adventures of Huckleberry Finn.
