Assignment abacus

A security leak in the multi-million-dollar Saturn Industries sends Boyd Maskell, a prospering junior executive and financial wizard, to an isolated house on the Scottish moors for a top-secret meeting designed to uncover the source. But when Maskell is transported to the site, he soon discovers himself a majority of one, and a strange series of visions and voices begins to make this cool young businessman doubt his own grasp on reality. Slowly, Maskell begins to realize that a means of escape lies in a secret code he carries in his packet of orders. His one hope is to crack the puzzle before his mind snaps.... A menacing tale of business chicanery and personal terror set against the lonely wilds of the Scottish lowlands.
