What is the name of the book where a mute boy is given the ability to speak and to live forever and he helps solve a mystery in the 1800's I think the authors name is Jacques?

Answer 1

It's called Castaways of the Flying Dutchman by Brian Jacques. There are two sequels also I think.

Answer 2

The book you are referring to is likely "The Invention of Hugo Cabret" by Brian Selznick. It tells the story of a boy named Hugo who is mute and is given the ability to speak. The story takes place in 1930s Paris, not the 1800s, and involves a mystery surrounding an automaton.
