Scotland Yard constable Susannah Foster (Rosalyn Lander) arrives in LA to help Hunter (Fred Dryer) and McCall (Stepfanie Kramer) in their investigation of a double murder. The victims were both prostitutes, and the murderer's MO matches that of a London-based serial killer who goes berserk to the tune of "Brahm's Lullaby." Can it be that a highborn British photographer is a modern-day Jack the Ripper? This episode affords the viewer the rare opportunity of hearing guest star Gary Sinise as he deploys a most convincing British accent! ~ Hal Erickson, Rovi
