H. G. Wells 
The Chronic Argonauts [EPUB ebook] 

A third-person narrator describes the arrival of a mysterious inventor to the peaceful Welsh town of Llyddwdd. Dr. Moses Nebogipfel takes up residence in a house neglected after the deaths of its former inhabitants. The simple rural folk become apprehensive about Nebogipfel’s activities in the house and suspect him of witchcraft. Ultimately they storm the inventor’s ‘devilish’ workshop. Nebogipfel escapes with the sympathetic Reverend Elijah Ulysses Cook, in what is later revealed to be a time machine.
The unnamed narrator later discovers the dazed Reverend Cook, who has been missing for three weeks. Cook becomes a second narrator, relating in flashback the night of his disappearance, and a series of subsequent adventures with Nebogipfel. He reveals that Nebogipfel is an ‘Anachronic Man’ whose genius drives him to seek out a time more suited to his abilities.
