Not quite in Grisham and Child’s league, but still heavy hitters are Nelson DeMille and Michael Connelly. In The Deserter  by DeMille, a Delta Force posted to Afghanistan disappear from his base.  He resurfaces in a video that shows him as a prisoner of the Taliban.  When he is spotted a year in Caracas, his capture looks for like desertion. Scott Brodie and Maggie Taylor are tasked with bringing him in.

In The Night Fire by Connelly, Harry Bosch is given an old murder book at a former partners funeral; his widow asks him to try and resolve the case.  Bosch, no longer with LAPD, relies on detective Rene Ballard to feed him information about the case. As they dig deeper, Bosch begins to wonder if his partner took the murder book to solve the case, or to put a lid on it.
