I was called to bees in a post box 3 or 4 years ago. It had been sealed up by the PO for a week or so before I got the call (small entrance hole at the bottom however). However mine consisted of a lot of faffing about to get the post box opened by a postman and the bees had gone.
There's a fair chance that there will be a queen in the swarm. A test-frame from a queenright colony could be tried and if there's no queen, you could unite to another stock and return the frame to where it came from. (Or even allow them to make a queen from it if you want more mistresses to look after).

May your bees read the same books as you do.
