He ran outside and waited for her in his cab, the door standing open, his foot ready to let in the clutch the moment she jumped in. But the seconds passed and she did not appear. Looking anxiously out and back he saw de Socotra come to the door of the apartment house with the four boys at his heels. He heard him say: "I tell you, she came down-stairs." "She didn't pass this way, sir." From the head of the steps they looked uncertainly up and down the street, and then went back into the building. Greg had drawn back out of sight. A moment later another cab drew up behind Greg, and two men got out. It was the puffy Abanez and another of the gang. At the same instant Amy, bareheaded, came running like a deer around the corner out of Ninety-fourth Street. The two men stared, rooted to the pavement in astonishment. Amy ran on to Greg's cab, but at the sight of the strange face, she drew back. "It's all right," he whispered swiftly. "It is I, Greg." She climbed in, he slammed the door, and they were off. De Socotra came running out of the building again. He met the two men on the sidewalk. All three jumped in the waiting cab and came on. CHAPTER XIV THROUGH THE STREETS Greg sped down the incline, made a wide turn into the Drive and headed down-town. As they circled they saw the other cab gathering headway. It had a more powerful engine than Greg's, and was in better condition. It ought to have overtaken Greg easily, but as they straightened out in the Drive it did not do so, but contented itself with maintaining a certain distance. Greg slowed down, and the following cab did likewise. "What's their game?" Greg asked himself a little anxiously. He rapped on the glass behind him to attract Amy's attention. She opened the door. "All right back there?" he asked cheerily. "I--I guess so," was the somewhat shaky reply. "Let down the front glass and we can talk better." She did so. "Have you got the little black book?" he asked eagerly. "No. I was surprised by his return. I dropped it in the back of the piano." "No one saw you drop it there,--Bianca?" "No, it's safe enough; if we can only find a way to get it out again. Where can we go now?" "To the yard." "He will follow us there." "Let him. We have plenty of friends there. He'll get a warm reception." They passed a policeman standing at the curb who glanced at them casually as they passed. They were not exceeding the speed limit now, or at least not by much. The other cab was a short block behind. Amy, who continually glanced back through the little window, gasped suddenly. "Oh, they're stopping! ... They're picking him up." "Who, the policeman?" said Greg. "By God! de Socotra has a nerve!" he added grimly. "They're coming on again! Oh, faster! faster!"
