i.e. The copyright owner could sue you if they found out and thought it worth doing, but the police wouldn't be interested.
However! I am not a lawyer! For real legal advice you'd need to ask (& pay) a lawyer.
Wait a minute aren't there companies out there right now that are making pdfs of our old books for a fee or have they been shut down? The paper book gets destroyed but you have a pdf to put on your ereader or convert it to word doc to print off if you want.
So long as that pdf remains in your custody, I don't see a problem with it.
