Castle is left wandering worrisome while Becket agrees, hush-hush and reluctantly, as only available detective fluent in Russian, to pose undercover as Elena Markov, prospective key employee of a Russian drug mob. Only there, she realizes it's not a safe office job, but hired killer, and she' put to the lethal test by enigmatic big boss Lazarus's ever-suspicious, trigger-happy lieutenant. The real Elena, who claimed being too frightened to join or act as double agent for the narcotics squad, meanwhile goes missing, and is likely to fatally identify Becket. While the desperate team fails to find her in time, utterly unexpected help proves vital, after she was astonished to meet a hated gang lord.
