You stop at Irving's room.  You can hear strange rustling noises from behind the door and a male voice murmuring something unintelligible.  It must be a thief!  You hear another voice.  Feminine this time.  It must be two thieves!  You grip your umbrella of doom tightly and take a deep breath.

Do you:

a) Try to stop the thieves (go to chapter 24)

b) Ignore them, Irving's plenty loaded (go to chapter 20)
