They got to the entrance to the apartment building and stepped into a
dark hallway. Then quite suddenly and apparently without thought the man
took a knife out of his pocket. "Suppose that man who darted into the
alleyway had intended to kill us," he thought. Opening the knife he
whirled about and struck his wife. He struck twice, a dozen
times--madly. There was a scream and his wife's body fell.

The janitor had neglected to light the gas in the lower hallway.
Afterward, the foreman decided that was the reason he did it, that and
the fact that the dark slinking figure of a man darted out of an
alleyway and then darted back again. "Surely," he told himself, "I could
never have done it had the gas been lighted."

He stood in the hallway thinking. His wife was dead and with her had
died her unborn child. There was a sound of doors opening in the
apartments above. For several minutes nothing happened. His wife and her
unborn child were dead--that was all.

He ran upstairs thinking quickly. In the darkness on the lower stairway
he had put the knife back into his pocket and, as it turned out later,
there was no blood on his hands or on his clothes. The knife he later
washed carefully in the bathroom, when the excitement had died down a
little. He told everyone the same story. "There has been a holdup," he
explained. "A man came slinking out of an alleyway and followed me and
my wife home. He followed us into the hallway of the building and there
was no light." The janitor had neglected to light the gas. Well there
had been a struggle and in the darkness his wife had been killed. He
could not tell how it had happened. "There was no light. The janitor had
neglected to light the gas," he kept saying.
