Memory Man Series (abridged)

Amos Decker's life changed forever - twice. The first time was on the gridiron. A big, towering athlete, he was the only person from his hometown of Burlington ever to go pro. But his career ended before it had a chance to begin. On his very first play, a violent helmet-to-helmet collision knocked him off the field for good and left him with an improbable side effect - he can never forget anything.

Something sinister is going on in Baronville. The rust belt town has seen four bizarre murders in the space of two weeks. Cryptic clues left at the scenes - obscure Bible verses, odd symbols - have the police stumped. Amos Decker and his FBI colleague Alex Jamison are in Baronville visiting Alex's sister and her family. It's a bleak place: a former mill and mining town with a crumbling economy and rampant opioid addiction. Decker has been there only a few hours when he stumbles on a horrific double murder scene.

Amos Decker and his FBI partner Alex Jamison are visiting his hometown of Burlington, Ohio, when he's approached by an unfamiliar man. But he instantly recognizes the man's name: Meryl Hawkins. He's the first person Decker ever arrested for murder back when he was a young detective. Though a dozen years in prison have left Hawkins unrecognizably aged and terminally ill, one thing hasn't changed: He maintains he never committed the murders. Could it be possible that Decker made a mistake all those years ago?

The sudden boom has also brought a slew of problems with it, including drugs, property crimes, prostitution—and now murder.
