WRITERS: VALERIE MAYHEW/VIVIAN MAYHEW
A devil-worshiping cosmetic surgeon in search of immortality compels his colleagues to commit murder through overly enthusiastic liposuction and chemical peels, turning a Windy City hospital unit into Chicago Hopeless. Creative casting:Richard Beymer (West Side Story, Twin Peaks) as the doc who takes face-lifts to a new dimension. Critique: Lots of juicy gore redeems this installment, but the fourth consecutive phoned-in performance by Duchovny and Anderson has us worried. B-
79. MUSINGS OF A CIGARETTE SMOKING MAN
In a Forrest Gumpian retrospective, Cancer Man reviews his life story through an eavesdropped conversation between Lone Gunman Frohike and Mulder and Scully. We are told of his seduction as an Army officer into the black forces, and that he is responsible for virtually every major historical event since then from Daley Plaza in 1963 to the Dorothy Chandler Pavilion every March.

Seems the rock contains 4-billion-year-old oily worms that transmit a deadly ''black cancer,'' and both America and the Russians want to exploit it. Historic moments: You thought the Cold War was over sorry. Smallpox vaccinations get another workout. More evidence that X's heir is the blond U.N. operative Marita Covarrubias (Laurie Holden). Plus, Mulder at his most intimate with Scully! Based on script alone: A-
