'and now it was too late' is this sentence valid?

won't the 'now' and 'was' conflict with each other?
Hello, JK!
I'd prefer: "and then it was too late"/"and now it's too late"
I don't like too much "now" and "was" either...
Let's wait til a native English speaker sees this...

'Now' can mean a past time which the speaker is referring.
(EX) Now it was too late. She had to die alone.
(EX) Now the war was practically concluded.

But then the whole context has to be in the past.

Yes. When 'now' is used with a verb in the past tense, it means some time before the speaker is speakng. This usage of 'now' is often used in narrating past events. When 'now' is used with a verb in the present tense, it means the time speaker is speaking.

OK, thanks, Paco!
