This is the world of ARMAND PTOLEMY, a new action-adventure hero. Facing an enemy armed with the Golden Aleph -- a mystical device that allows its wielder to see holographically into every point in time and space, Ptolemy must use every trick of his Oxford-educated mind and circus-trained body to succeed.
