Prodigy

S2, E4: Jack and the team search for a brilliant but complicated 14-year-old Russian violinist, Natasha Tzetcovich (Elizabeth Rice), who disappeared after a rehearsal for an important concert appearance. Their investigation uncovers that Natasha was experiencing panic attacks resulting from the pressure to perform that her immigrant parents put on her. Natasha was involved with her manager's son, a troubled boy who supplied the young artist with drugs. The boy also disappeared at the same time as Natasha. And a strange man whom her parents may have known from Russia has been stalking the girl and sending her e-mails from every city in which she has played in the last year.
