It took Rob a few minutes to walk the short distance to Spielbudenstrasse. He stood in a dark alleyway for another few minutes watching the people walking up and down the street past Luftballon. There was an alley at the side of the club which looked as if it would give access to the back of the building and having assured himself that he would not be noticed, Rob crossed the road and slipped into the alley. He crept carefully towards what looked like the rear entrance to the club, taking care not to disturb any rubbish lying on the ground as he went.
The side entrance was opposite a recess which gave access to an outhouse and just beyond the door was a small window situated high up on the wall. It had clear glass, so was unlikely to be a toilet, but Rob could not see in from ground level
