Devlin investigates a missing Salvadoran's gruesome fate Devlin Kirk and his partner Bunchcroft are Denver's finest industrial security experts, even if Denver doesn't see it that way. Their last big case got them out of debt, but since then the well has been dry. Their firm is teetering on the edge of bankruptcy when Nestor Calamaro, a young illegal immigrant whose family is close to Bunch, disappears. Kirk can't afford any pro bono work, but Bunch talks him into the good deed. Missing persons cases are usually simple. This one is not. Nestor's trail leads Kirk and Bunch to two more missing immigrants, all of whom are connected to Antibodies Research, a biotech start-up whose work is shrouded in extreme secrecy. For Kirk and Bunch, penetrating their security system is the easy part. But when they learn the terrible truth behind Nestor's disappearance, they risk becoming missing persons themselves.
