A revolver butt tapped the side of the house.

"Coming," replied Hal.
Again silence; but this time broken from an unexpected source.

"Help!"
Just that one word; that was all. Again a revolver butt crashed upon the
Austrian's head and he subsided without a murmur.
But the one word had given the warning.
