this time London was agog with the exploits of Jack the Ripper.
One theory of the motive of the murderer was that he was
performing an Operation to obtain the Supreme Black Magical
Power. The seven women had to be killed so that their seven
bodies formed a "Calvary cross of seven points" with its head to
the west. The theory was that after killing the third or the
fourth, I forget which, the murderer acquired the power of
invisibility, and this was confirmed by the fact that in one
case a policeman heard the shrieks of the dying woman and
reached her before life was extinct, yet she lay in a
cul-de-sac, with no possible exit save to the street; and
the policeman saw no signs of the assassin, thought he was
patrolling outside, expressly on the lookout.
