My head was humming with my discovery.

I remembered Gresson's word to his friend: 'Tomorrow night.' As I read it, the Portuguese Jew had taken a message from Gresson to someone, and that someone had come from somewhere and picked it up.

The message contained an assignation for this very night.

I had found a point of observation, for no one was likely to come near my cave, which was reached from the moor by such a toilsome climb.

There I should bivouac and see what the darkness brought forth.
