"But then," she added in a lighter tone, "you know him. Gets going on something and forgets everything else. He'll show up." "Yes," Johnny agreed, "he's bound to." Johnny was thinking of the time the veteran detective had turned himself into a gray shadow and had, all unknown, dogged Johnny's heels, saving him from all manner of terrible deaths. The time was to come, and that soon enough, when he was to wish the "Gray Shadow" back on his trail. "Drew," Johnny said, turning to his sturdy young friend, "I came here the moment I reached the city. How come the place was locked up and dark?" "Been on a vacation; just got back." Drew's face lighted. "Went to the Rockies. Had some wonderful hunting--grizzly bears. Can't say that's more exciting than hunting crooks, though," he laughed. "Met a girl you'd like on the way back." Drew Lane turned to Joyce. "Came on the bus. People in a bus, traveling far, get to be like one big family. Funny part was--" He gave a low chuckle. "She's coming here to help her uncle. He has a store on Maxwell Street. Maxwell Street! Can you imagine?" "Rags, scrap-iron, poultry in crates, fish smells and noise--that's what Maxwell Street means to me!" Joyce shuddered. "Just that!" Drew agreed. "This truly nice girl from somewhere in Kansas is going there to help in her uncle's store. She doesn't know a thing about Chicago. Thinks Maxwell Street is all the same as State Street, I'm sure. Believes her uncle's store is anyway six stories high. Well, she's in for a terrible shock. I feel sorry for her. Have to get round and see her--gave me the address. She asked me what I did in Chicago." Drew chuckled once more. "What did you tell her?" Joyce asked. "Said I looked after people, lots of them." "And for once you told the truth," Johnny laughed. "But Johnny!" Joyce exclaimed. "Tell me some more about this 'House of Magic' you've discovered. Sounds frightfully interesting. We all thought you were a little delirious when you first talked of it. But now--" "Now you begin to believe me." Johnny's eyes shone. "It's a truly wonderful place." "Tell us about it." Captain Burns insisted from his corner. "Heard about some of these things before. Shouldn't wonder if they'd do things in the end to lift the load off us poor, over-worked detectives." "I'll tell you all I know, which isn't much," Johnny agreed. And here I think we may safely leave our friends for a little time while we look in upon Grace Krowl, the girl from somewhere in Kansas. She had found her uncle's store on Maxwell Street. And how she had found it! CHAPTER VI A STORE IN CHICAGO A slender mite of a girl, barely past her eighteenth birthday, Grace Krowl was possessed of an indomitable spirit and a will of her own; else she would not have been walking down Maxwell Street in Chicago hundreds of miles from her home, in Kansas.
