Havelock slips up to the office with remarkable discretion, considering he has to cross the crowded bar to do so. The illogical Milliways shadows help, but mostly it's a matter of thinking yourself unnoticeable - which, in Havelock's opinion, he could always use some work on.

He hesitates, then knocks on the door to see if anyone is in there. He doesn't exactly want to post a note on the notice board, and delivering a letter through Bar does have the down side that whoever receives it will probably read it out in the open.

He could slip a note underneath, he supposes... but really, if possible, better not.
