This is different in different languages, and perhaps also in different varieties of English (Brit/American English) Often you get to see a quotation mark at the opening of every new paragraph but endquote only at the very end, like this:

"You bastard,
"I never thought you'd deceive me like this, what a trickster you are!
"Have you been writing this for a long time?"

This is common in French too. But often it works fine to just put a " at the opening of the quote and another at the end, no matter how long the quoted statement is.
