Mask of Murder" (1985)
Rod Taylor plays Inspector McLane in this obscure slasher flick also
known as "The Investigator."
Although set in a Canadian town, everything was filmed in Stockholm and
Uppsala, Sweden (director Arne Mattson's hometown) during the winter.
Fairly early in the film, the cops corner a serial killer who's been
slashing pretty girls. Chief Rich (Christopher Lee) wants the culprit taken
alive, but when gunfire erupts, Inspector McLane blows the killer away.
That's just the beginning of the mystery, however, as the murders of
young women begin again. With Chief Rich hospitalized with a bullet wound,
McLane leads the investigation into who the copycat killer is. Adding to
his stress is his cheating wife (Valerie Perrine), who is rendezvousing
with a detective colleague of McLane's.
It's violent movie with a low-budget feel that's surprisingly satisfying,
and the mystery kept me guessing till the end.
