The story is about Jack Fitzpatrick, a salesman and degenerate gambler, who tries to keep his head above water while dealing with illegal bookies, the FBI, and a possibility of making a huge multi-million dollar sale that will help get his finances back in order.
The Plot
Priest is a businessman, so naturally there's plenty of business-related material in the book, as well. The business aspect involves Fitzpatrick attempting to land several large software sales, while learning there's something shady taking place at his company.
Summary
The dialogue is rather stilted at times, which isn't that surprising, as even long-time, best-selling authors have more difficulty with dialogue than any other aspect of writing.
A decent plot makes up for any other shortcomings, however, so there are plenty of worse ways you could spend your time than by reading Decisions.
