Necesito una historia con los verbos modales y luego esplicarla?

Nobody knew what Adam had in his suitcase.

That extravagant, carmine, leather suitcase ; that was for sure his most valuable property, what could be inside it?

As every day, Adam left his flat at 5o'clock in the morning to catch the train, he couldn't resist arriving late.

But, where?

He might be going to some kind of secret job.

That day something was different, he didn´t have his suitcase with him.

He should be more careful with his flat, but it was the most unpleasant place to be in, but, somehow, someone entered the building.

The person who entered could have found the suitcase and he might discovered what was inside it, but he never came out of the flat.

It's believed that Adam returned and when he found the invasor he had to get rid of him because he found his deepest secret.

We still don't know what can be inside the suitcase.

Espero te sirva!
