The Fallen (2018) is book #4 in the Amos Decker Memory Man series by David Baldacci.
Star FBI detective Amos Decker and his colleague Alex Jamison must solve four increasingly bizarre murders in a dying rust belt town–and the closer they come to the truth, the deadlier it gets …
… It’s a bleak place: a former mill and mining town with a crumbling economy and rampant opioid addiction. Decker has only been there a few hours when he stumbles on a horrific double murder scene. …davidbaldacci..com
There’s much to like about this book.
Decker is brilliant but socially awkward due to brain injury from an old football hit.
In this one he finally starts showing some empathy to other people, one 6-year-old girl in particular.
BUT … the plot is still 40% too long and complicated. Baldacci needs a more ruthless editor.
