"The first thing to do is tie this fellow up," said Anderson, indicating the Bulgarian.
Ivan stepped forward, and taking a piece of rope that Helen gave him, tied the man up tightly.
"Now," said Chester, "to your posts. We don't want to be caught unguarded."
All took the places assigned them and examined their weapons. An hour passed. Then Chester, peering through the window, exclaimed:
"Here they come!"
CHAPTER XXIII.
THE FIGHT IN THE HOUSE.
"I'm ready for them!" shouted Ivan, from his position behind the broken door.
He stood well back in the darkness, out of sight from beyond the house.
All was quiet and dark within, for with the appearance of the first of the enemy Chester had extinguished the light. The figures of the approaching Bulgarians were plainly visible to Chester and Helen through the windows. Ivan and Colonel Anderson, of course, could not see them, although they would have been visible to the former had he a mind to take a chance and expose himself to their view.
