all of these

Hi,

could you please tell me if the following is correct

It is a comedy, a triller and and a novel of manner - all of these at the same time.

I am particularly interested in finding out wheter “all of these” works fine in this sentence.

Cheers

‘All of these’ is okay but I don’t understand the term ‘novel of manner’ at all.

Thanks you!

It should be novel of manners:) Wikipedie has an article about this literary genre:
