I had an idea for a trilogy of novels with the first written in the past tense, the second in the present tense, and the third in the future tense. Why hasn't anyone done this before? I thought. Then I realised what you wouldn't be able to do in the third book. In the first, you could say:
He walked along the street. He had just left his house, and later it would be burgled.
In the second:
He walks along the street. He has just left his house, and later it will be burgled.
But in the third:
He will walk along the street. He will have just left his house, and later it what? burgled.
Without a 'future in the future' tense, this idea can't work! Has there ever been any such tense in the English language, or is there some sort of substitute for one? The closest I've come up with is:
He will walk along the street. He will have just left his house, and later it will be going to be burgled.
… which is cumbersome to say the least!
Edit: my example was badly chosen, because of the adverb 'later'. Since I'm toying with the idea of a whole book written in the future tense (or 'tense' if you don't count periphrastic tenses as tenses 🙂 ), I'm looking for something that works in general, not just for this sentence. A better example is:
He left his house, but he would return / He leaves his house, but he will return.
Now 'He will leave his house, but he will return' doesn't really work.
