A review from IMDb.com:

Since this black and white B flick is only
under an hour I doubt that it will ever see
the light of day on video. It's too bad since
it is an unusual and tidy little mystery of
the late 1940's. A Seer (fortune-teller)
brilliantly played by Fritz Leiber predicts
that a young girl (Mary Beth Hughes) will
encounter tragedy on a train. It all comes
together when a man (Charles Russell) fleeing
from the law for a murder hides out in a
boarding house. Other than the gorgeous
Miss Hughes and handsome Mr Russell the
boarders include the delightful Nana Bryant,
feisty Lee Patrick, freckled faced kid Dale
Belding and Billy House. Above-par B film
fare especially for Noir fans. - banse
