McGill and Gropper are back for another adventure! McGill never leaves the diner, drinks coffee, and eats pancakes/bacon, while Gropper is in charge of the heavy lifting. Both men wouldn't have it any other way.

As they've gotten older, times have changed. While Gropper has led a transient life, moving from place to place to protect the people he cares about, he's longing to settle down. Meanwhile, McGill must handle the interest of a young South Carolina Law Enforcement Division officer, Lorraine Littlefeather, who would rather see him behind bars.

After a big case comes their way, they need to investigate the mysterious deaths of medical workers. And Gropper's friend Connie, and her daughter Liz, might be next on the list.
