Peter Ash's friend Lewis has helped him out of jam more times than he can count, and has saved his life more than once. So he doesn't hesitate when Lewis asks a favor. Lewis has left his criminal past behind, but a former associate may be in trouble, and he and Peter must make a trip to check in on the man. But their visit immediately takes a dark turn when they arrive to find a smoldering cabin. They soon realize that someone has stolen notebooks full of incriminating secrets about Lewis's long-ago crimes.

Lewis and Peter must find the notebooks: They are full of details that not only endanger the family and home that Lewis has built, but place his very life at risk. With June's help, they begin to search. Soon they find themselves up against professional criminals, and the two men may have to tap into the dark sides that they have worked to keep hidden in order to take on particularly ruthless enemies.
