This is straightforward stuff. the blighter has got hold of super-classified info about our missile strength! 3 SATURN inter-continentals and 1 large CRUISE MISSILE. He`s also latched on to our delivery difficulties with the new cataclysmic, laser-equipped sock-melting FRIGHT missile.

2. 4 Wed
At first my chief aid, 33TWiTT linked this with the installation of Westmacott Exponential Dishwashers in the House of Commons Cafeteria.

Then it dawned - it`s an instruction to waiting troops, poised to attack. For `4 WED` read `FORWARD`. Simple.
Only problem is where are they and who are they going to attack?

"Yes? Ah, come for the milk money, have you? Just a moment while I get my....... aaaagh!!"
