Tiger's Code

Tiger's Code by Betty J. Vaughn
Quint Cord's latest assignment is proving to be his most challenging and could well lead to catastrophic events if he doesn't break the code in time to avert them.
Quint Cord is an unlikely spy. With sufficient family money so that he never needs to work, he could have spent his life idling on a beach chasing women. But from the moment he discovers famous codes of the past in a university class, he is hooked. His unique talent for creating and breaking codes brings him to the attention of the CIA.
A powerful and ambitious politician, who's in cahoots with a Saudi prince, plans to seize the US presidency and throw the western world into turmoil. Quint flees the country only to stay one step ahead of a foe determined to kill him before he can break the code.
Clue by clue, Quint begins to zero in on his target but can he stop him in time?
