No power at ignition 93 crown vic

I bought this car at auction and it started and ran fine ( old police car). I drove it home and it sat in my driveway for months but I started it once in a while to mow around it. One day it wouldn't start. No power at the ignition but everything else works, what's with that??? There is nothing, not even a click. Lets assume the battery and starter are good -Is there a fusable link? Where would it be? What else could it be?
Any ideas?? Thanks Cheryl

There is a starter cicuit fuse under the hood, look on the inside of the fuse cover for it. But before you do that bang on the starter with a hammer or something else, starters have a way of freezing up if left to long.
