The murder at the center of this episode is that of an insurance executive. The killer may well be the father of a nine-year-old leukemia victim, to whom the victim denied funding for special treatment. In their efforts to prosecute the case, A.D.A.'s McCoy (Sam Waterston) and Southerlyn (Elisabeth Rohm) find themselves figuratively handling a double-edged sword. ~ Hal Erickson, Rovi
