A mouse trap turned up missing a few days ago from a kitchen counter. I'm

Oddly, no noises at night. No sign of the mouse where I've looked in the
kitchen. Wonder how long this will last before I smell a dead mouse?

It could be you also have rats. Rats eat dead mice and can drag that
trap a long distance.
