"92 Stuyvesant Square."

Greg was reminded of Pa Simmons' first report that day.

Meanwhile de Socotra and his two henchmen bade each other courteous farewells. Abanez and the other expressed a fervent hope that the young lady would be better in the morning—Greg smiled to himself at the grim comedy. The two Spanish-Americans got into the flivver, and de Socotra handed Amy into the other taxi. The policeman seated himself by the chauffeur to ride back to his beat. They started simultaneously, Greg turning down-town, the other keeping on up the Drive. The bystanders remembered their suppers and melted away.

Greg made the best time he could, for he was wildly eager to get back to the Stickney Arms, but he had to humor the old flivver now. She was like a broken-winded horse. Stuyvesant Square, as everybody knows, is one of the last haunts of old-fashioned respectability away down town. It was a good four mile drive, and Greg chafed bitterly at the time he was losing.

A broad and well-lighted street with a trolley line bisects the Square, but around the sides it is dim, respectable and lonely. Greg privately determined that nothing should induce him to leave his cab. Greg looked in vain for Number 92. Having made a complete circuit of the Square he was satisfied there was no such number.

He stopped and notified his fares. "Do you know the house you want to go to?" he asked them.

Abanez replied: "Yes, it's on the east side. Drive slowly up that side and I'll point it out to you."

Near the top of this side of the Square he called Greg's attention to a tall narrow house with a brownstone front, and Greg drew up before it. No lights showed in any of the windows; to Greg it looked like an unoccupied house. His fares did not immediately get out, and Greg looked around to see what they were waiting for. The window behind him was still open.

"Wait a minute," said Abanez, "we have not quite finished our talk."

At the moment the significance of this maneuver did not occur to Greg. Afterwards he remembered that a man was passing on the sidewalk. They waited until he turned the corner.
