Foster Twins In The Mystery At Moore's Lake

The dark night was strangely quiet. The moon had disappeared behind the clouds, and there were absolutely no sounds. Not just quiet, but total silence. Then the lonesome cry of a whippoorwill broke the silence. Or was it really a whippoorwill!

A strange ghost-like figure appears during the night as the twins and their cousin are camping in the Ozark Mountains above Moore's Lake near Heber Springs, Arkansas. Akiela, the last of a mysterious tribe of Native Americans, has come to warn the young adventurers about evil men in the area of the lake. He seems to be able to appear and disappear at will. He is very tall, and pale, almost deathlike...his long white hair flowing to his narrow shoulders. His eyes burn with agitation and displeasure at what is happening to his beloved mountains.
