Mole Free Zone or What ?

I was woken by a stillness.....and in the streets of the Dock nothing seemed to stir.......had everybody gone on the last ferry, left the Town and forgot to switch off the lights, gone shopping in Haverfordwest or to the Three Crowns for a free beer....what had caused this mass exodus.......up and down the street we roamed and not a sign of even a rodent..........Is this the end ......... or a new beginning........No silly me..........Its must be Christmas Day............in Pembroke Dock
