This he skirted for some distance, squeezing between the cliff and the brambles until he came at last to a spot where all further progress appeared to be impossible.
'Can you see a light behind us ?' asked my companion.
I turned round and looked carefully in every direction, but was unable to see one.
'Never mind,' said he.

'You go first, and I will follow.' In some way during the instant that my back had been turned he had swung aside or plucked out the tangle of bush which had barred our way.

When I turned there was a square dark opening in the white glimmering wall in front of us.
'It is small at the entrance, but it grows larger further in,' said he.
I hesitated for an instant.

Whither was it that this strange man was leading me?
Did he live in a cave like a wild beast, or was this some trap into which he was luring me?
The moon shone out at the instant, and in its silver light this black, silent porthole looked inexpressibly cheerless and menacing.
'You have gone rather far to turn back, my good friend,' said my companion.

'You must either trust me altogether or not trust me at all.' 'I am at your disposal.' 'Pass in then, and I shall follow.' I crept into the narrow passage, which was so low that I had to crawl down it upon my hands and knees.
