"A Rick Bentz/Reuben Montoya novel"--cover.

It was one of the most brutal cases of Rick Bent's career. The 21 Killer's victims were always twins, abducted just before their twenty-first birthday. As far as the LAPD is concerned, the 21 Killer is safely behind bars. Psychologist Brianna Hayward, whose cousin was found guilty of the crimes, is desperate to convince the New Orleans police otherwise. Bentz had doubts about the conviction when he worked the case in L.A. Now the real murderer may be loose in Bentz's backyard. Twin sisters from All Saints College have vanished without a trace, days before their birthday. And as Bentz and his partner, Reuben Montoya, follow the trail through bayous and backstreets, a killer prepares to unite his next victims in death forever.
