THE WIDE WINDOW: by Lemony Snicket:

Violet (inventor), Klaus ( reader) and Sunny (biter) were sent to live with uncle Josephine. She lived on the edge of a hill. She was a total grammar freak and was afraid of everything. But the Baudelaire children were happy because they felt secure, until one day, they came to a market and meet Captain Sham (Count Olaf in disguise). But Josephine didn't believe the children. One day, Aunt Josephine died, leaving the three of them to Captain Sham. But the three Baudelaire children discovered that Josephine was still alive and was hiding. Once they fount her they sailed back with a boat, but the leeches ate the boat. Fortunately, Sham saved them but immediately after threw Josephine in the water and she died. Then when Mr. Poe and Sham were talking about the Baudelaire children, Sunny ate Shams wooden leg and everybody knew that it was count Olaf in disguise.
