why should it, anyway?" The other made no answer; he swerved the car abruptly off the avenue, into one of the nondescript side streets. He drove swiftly to the corner, turned south again, and turned again on some street Pat failed to identify--South Superior or Grand, she thought. They were scarcely a block from the magnificence of Michigan Avenue and its skyscrapers, its brilliant lights, and its teeming night traffic, yet here they moved down a deserted dark thoroughfare, a street lined with ramshackle wooden houses intermingled with mean little shops.
