Pepperman's Promise—Prequel –This contemporary fiction story is not a mystery, but lays the groundwork for the characters introduced throughout the mystery series.

In 1966, Jim Pepperman comes home from practice to the news that his dad has died in an oil rig accident. Not only has the high school football star lost his mentor and best friend, but when his mom moves the family from Texas to New Jersey, he's forced to say goodbye to his home, his team, and his chance for a football scholarship.
Facing senior year in a new school with no friends, Jim struggles to keep the promise he made after his dad died to be a substitute father for his two younger sisters and a shoulder for his mom. But stepping into his dad's shoes at seventeen feels impossible, the same way giving up the dream to play pro ball is harder than Jim thought. And senior year is just the beginning.

Perplexity-Book One

Retired pro football player Jim Pepperman is about to lose everything to the secret he's locked down for eleven years—that he got into a bar fight with a stranger and might've left him for dead. It doesn't really matter that it was self-defense. Nightmares are stealing Jim's sanity, guilt is carving out pieces of his soul, and his silence is driving a wedge between him and his wife. Desperate to confess, he visits his dad's grave and tells the only person he can. When Jim is almost shot leaving the cemetery and letters threatening his life show up, he begins to wonder if someone has finally discovered what happened that night.
Ex-Air Force Colonel Sean Halpin is an intelligent, meticulous, special investigator for the Newark Police Department. Assigned to Jim's case, it's Halpin's job to sift through clues that make no sense. As the threats escalate, he's put on a countdown to uncover the real story before it's too late. But his top two suspects have iron-clad alibis, and Jim may be covering up the crucial evidence Halpin needs to save his life.
