Nick removed one of them. Then he made his rope fast, and crept through the space where the glass had been.
The Jones' flat was next to the top, so Nick had a short descent.
But there was an awful stretch of empty air under him as he hung there.
The shaft went to the basement floor, about seventy feet below the level of the window which opened into the room occupied by the Jones' new servant.
He found that window readily. One glance through it was enough to satisfy him.
There sat the colored girl, reading a book. Nick's suspicions had been correct.
Naturally he did not delay very long in the air shaft. He had a hard climb to make, hand over hand, to the roof.
The instant that his eyes rested on the girl, he began the ascent.
He had gone up less than six feet when the rope suddenly gave way, and he found himself plunging downward through the shaft.
