I would like to learn whether or not there is any connotation held by the phrase 'after which' when used to start a sentence.
I recently read 'The Hundred-Year-Old Man Who Climbed Out of The Window and Disappeared' where this is heavily used. The overall tone in the book, which seems to be somewhat humorous and unserious to me, makes me think that the wording in question possesses an comical undertone.
Is this true?
'After which Allan retired for the night.'
Note that I am not a native-speaker, thus I'm having hard times understanding such 'undertone' every now and then.
