村上春樹のUndergroundを読んでいます。
After the drug initiation everyone was dead tired, so the door was left open for a time. I wasn't too zonked out by then so I prepared a change of clothes and after making sure
the coast was clear, dressed and crept out of the building. There were guards, but I managed to
give them the slip.
