Synopsis:
Museum curator Ferlin Nyxly discovers a harp with a demon's face on it. After playing the harp, it grants him his wish to become a concert pianist. In doing so, famous pianist Timos Achens losing his own ability to play. Nyxly then sets up a concert in Metropolis attended by Clark Kent and Lois Lane. When assassins strike, Superman goes into action drawing the attention of the crowd away from Nyxly.

Nyxly becomes jealous of Superman. Once again he uses the harp. This time he steals Superman's ability to fly. Nyxly then uses his new power to steal cash from an armored car. Superman doesn't know the source of his power loss. He suspects the sand creature which has appeared once again may be responsible.

Nyxly then steals more of Superman's powers and challenges him to a fight. Without many of his powers, Superman still meets the challenge, but he is now outmatched. Then the sand creature appears and destroys Nyxly's harp. Superman's powers return, but he remains puzzled concerning the sand creature's motives.
