Afghan refugee Sari Nazeri, who was allowed to immigrate after warning US troops Taliban bombing, is found murdered, mutilated near-unrecognizable and dumped in sludge, which can only be studied properly thanks to lampreys who fed on her otherwise lost flesh. She's ID'ed by surgical implant serial number, the cause of death is hard to work out. Her brother Aziz is furious, even before Booth, who works on the case with CIA acquaintance Danny Beck, who for once must cede jurisdiction, works out the dreaded terrorist presumed killed by drone attack is probably in the country and after them.
