72. The Investigators W.E.B. Griffin 1997
Badge of Honor- Det. Payne solves 2 cases and commits gross penis misconduct. However, the felon he's involved with just happens to succumb in a shoot out at the end of the book. 2 books, 2 dead girlfriends.
This one strained credulity even more than a normal thriller or other Griffin books. It weighs in at 578 pp, and unless you're reading the whole series, I wouldn't recommend it.
