then I got myself together in the middle of the pentacles, feeling
horribly gone and shaken, and glancing 'round and 'round the barrier; but
the thing had vanished. Yet, I had learnt something, for I knew now that
the Grey Room was haunted by a monstrous hand.

"Suddenly, as I crouched there, I saw what had so nearly given the
monster an opening through the barrier. In my movements within the

foolishness--it had been enabled for a second time to pass the outer
