Bobbie, with a left-ward twitch of his head, and a slight quiver of the lid of his left eye, brought an attentive ear close to his mouth.

"My boy, I want you to go outside and have the taxicab starter reserve a machine for 'Mr. Green.' Tell him to have it run forward and clear of the awning in front of the restaurant—slip him this other dollar, now, and impress on him that I want that car about twenty-five feet to the right of the door as you go out."

The waiter nodded, and leered slyly.

"All right, sir—I get ye, Mr. Green. It's a quick getaway, is that it?"

"Exactly," answered Bobbie, "and I want the chauffeur to have all his juice on—the engine cranked and ready for another Vanderbilt Cup Race." Bobbie gave the waiter one of his best smiles—behind that smile was a manful look, a kindliness of character and a great power of purpose, which rang true, even to this blasé and cynical dispenser of the grape. The latter nodded and smiled, albeit flabbily, into the winsome eyes of the young officer.

"Ye're a reg'lar fellar, Mr. Green, I kin see that! Trust me to have a lightning conductor fer you—with his lamps lit and burning. These nighthawk taxis around here make most of their mazuma by this fly stuff—generally the souses ain't got enough left for a taxicab, and it's a waste o' time stickin' 'em up since the rubes are so easy with the taxi meter. But just look out for a little badger work on the chauffeur when ye git through with 'im."

Burke nodded. Then he added. "Just keep this to yourself, won't you? There's nothing crooked about it—I'm trying to do some one a good turn. Tell them to keep the taxi ready, no matter how long it takes."

"Sure and I will, Mr. Green."

The waiter walked away toward the front door, where he carried out Burke's instructions, slipping the second bill into the willing hand of the starter.

As he came back he shrewdly studied the face of the young policeman who was quietly listening to the furious fusillade of the ragtime musicians.
