d buildings,
residences, most of them, of a generation passed away. Sanford Quest
entered the house with a latch-key. He glanced into two of the rooms on
the ground-floor, in which telegraph and telephone operators sat at their
instruments. Then, by means of a small elevator, he ascended to the top
story and, using another key, entered a large apartment wrapped in gloom
until, as he crossed the threshold, he touched the switches of the
electric lights. One realised then that this was a man of taste. The
furniture and appointments of the room were of dark oak. The panelled
walls were hung with a few choice engravings. There were books and papers
about, a piano in the corner. A door at the further end led into what
seemed to be a sleeping-apartment. Quest drew up an easy-chair to the
wide-flung window, touching a bell as he crossed the room. In a few
moments the door was opened and closed noiselessly. A young woman entered
with a little bundle of papers in her hand.

"Anything for me, Laura?" he asked.

"I don't believe you will think so, Mr. Quest," she answered calmly.

She drew a small table and a reading lamp to his side and stood quietly
waiting. Her eyes followed Quest's as he glanced through the letters, her
expression matched his. She was tall, dark, good-looking in a massive way,
with a splendid, almost unfeminine strength in her firm, shapely mouth and
brilliant eyes. Her manner was a little brusque but her voice pleasant.
She was one of those who had learnt the art of silence.

The criminologist glanced through the papers quickly and sorted them into
two little heaps.

"Send these," he directed, "to the police-station. There is nothing in
them which calls for outside intervention. They are all matters which had
better take their normal course. To the others simply reply that the
matter they refer to does not interest me. No further enquiries?"

"Nothing, Mr. Quest."

She left the room almost noiselessly. Quest took down a volume from the
swinging book-case by his side, and drew the reading lamp a little closer
to his right shoulder. Before he opened the volume, however, he looked for
a few moments steadfastly out across the sea of roofs, the network of
telephone and telegraph wires, to where the lights of Broadway seemed to
eat their way into the sky. Around him, the night life of the great city
spread itself out in waves of gilded vice and black and sordid crime. Its
many voices fell upon deaf ears. Unt
