The last place Manny Rupert wants to go is prison. But when the opportunity arises to investigate an inmate's claim to be Nazi war criminal Dr. Josef Mengele, it's too much for the ex-cop-turned-PI—last seen in 2002's Plainclothes Dead
—to pass up. Masquerading as a drug counselor—despite his own addictions—Manny meets the nonagenarian who calls himself Mengele and hears firsthand of the torturous experiments the “Angel of Death” conducted at Auschwitz. Add to the mix the reappearance of Manny's ex-wife, Tina, whom he sees cavorting in the conjugal trailer with the prison's resident Jewish skinhead. It turns out that Tina not only works for an Internet Christian escort service secretly run by one of the prisoners but is also in league with the same man who hired Manny to spy on Mengele. Lines soon blur between justified revenge and outright cruelty, and it's up to Manny to keep everything straight or die trying. Stahl is no stranger to smashing social taboos, and his trademark blend of ballsy, blacker-than-black humor and wry social commentary lets him find humor in the Third Reich. (Mar.)
