He had been blown up twice already.

While he slept his wife heard some one moving in the hall.
Looking out through a small window, she saw the ex-employee fumble with something and then turn out the gas on the landing.

Her husband, awakened by her exit and return, asked sleepily what the matter was.
"I saw Rizzi out in the hall," she answered.

"It was funny-he put out the light!" In a moment the milkman was out of bed and gazing, with his wife, into the street.

They saw Rizzi come down with his tray and pass out of sight.
