In his senior year in college, star athlete Mitch Prudene has a perfect grade-point average, a full scholarship to law school, a beautiful girlfriend . and a secret that will doom everything if anyone finds out about it. Unfortunately, Mitch's worst fears are realized when the mysterious Ace Nagle shows up. Like a card cheat who has the deck stacked, Nagle not only knows Mitch's secret, but seems to know everything else about him, too-all of his weaknesses and exactly how to manipulate him. Threatening to go to the police with the information he has, Nagle blackmails Mitch-only instead of money, he demands that Mitch perform a series of illegal favors. So begins a sinister cycle of extortion where each crime Mitch commits for Nagle becomes new ammunition for Nagle to use against Mitch . and the only way out is for Mitch to find out who Nagle really is and what he's after. In the spirit of such thrillers as Cape Fear and Fatal Attraction, Nagle's Mercy is a page-turning rollercoaster ride of white-knuckle suspense.
