"Did you get the letter all right, Carl?" asked Matt, as soon as the Dutch boy had come close.
"You bed my life!" whooped Carl. "Don'd I chenerally ged vatefer I go afder, Matt?"
"It isn't often you fall down, and that's a fact."
"It wasn't much of a job, anyhow," laughed Ferral, "going after something that was waiting for you."
"I vent so kevick as I got pack," continued Carl, drawing the letter from his pocket, "und dot's vere I shine. Motor Matt say for me to do somet'ing, und I do him like chain lighdings. Dere you vas. He's atressed to Misder Motor Matt, care oof der Lestrange Garage, und down in vone gorner iss der vort 'imbortant.' My nerfs vas all in some flutters to know vat iss on der insite."
Matt took the letter and tore it open; then, for the benefit of Harris and Ferral and Carl, he read it aloud.
"'Motor Matt: You are a friend of Helen Brady's, and the writer knows that she is in grave peril. She can be rescued, but it can only be by means of your air ship, the Hawk, and the work will have to be done quietly. I am one of the detectives from headquarters, and my attention is so completely taken up with the case that I can't leave where I am to call and see you personally, but if you want to help rescue the girl, you will follow these instructions:
"'Between La Grange and the town of Gary, not many miles from South Chicago, there's an abandoned stone quarry. You can't miss it, as it is on the Drainage Canal, and the limestone in the bottom of the quarry will look like a white patch on the earth from the air ship. Bring the Hawk to the quarry at ten o'clock to-night, descending on the edge of the Canal. I will be there to meet you. Don't come before night, for, if the Hawk is seen, we will have all our trouble for our pains. And keep mum about what you are doing, for if you were to talk, the information might reach those who have the girl in charge and thus prevent our success. Can I count on you? I am figuring that you will receive this letter Tuesday, and come to the quarry Tuesday night; but, if you don't receive this until Wednesday, come Wednesday night.
Dave Glennie.'"
"Egol!" muttered Harris. "That's a peculiar letter, and no mistake. But it rings true. Besides, I know Glennie, and he's the best detective at the city headquarters."
"I had hoped that this might be from Miss Brady herself," said Matt.
"The girl is probably where she can't write. Glennie knows what he's about. He has asked you to come and told you how to get to the place, so if you want to help Miss Brady, Matt, you'll go."
