It was definitely a capital-K Knock, the kind of knock they Foley in for police flicks, with a lot of ominous reverb that cuts off sharply, whang, whang, whang. The thunder of authority on two legs. It even penetrated my headphones, shook all the way down to my balls with the premonition of something awful about to come. I slipped the headphones around my neck, hit the panic-button key-combo that put my lappie into paranoid lockdown, unmounting the encrypted disks and rebooting into a sanitized OS that had a bunch of plausible homework assignments and some innocent messages to my mates (all randomly generated). I as- sumed.
