Result of a sleepless night (or morning)...

Here I am, up at this ungodly hour after a night of oil-burning and tea-guzzling. The windows are shut, the doors locked and the blinds drawn after a recent encounter with a thief. So I am not able to discern the usual twittering (the natural variety) activity that usually happens outside at this twilight hour. But I digress...
This time around, the puzzle might come across as a tough cryptic nut for the newly initiated. The gloves are off, people!
Enjoy... or not!
