Beside him as he wrote, stood a man whom he recognized--one Brown, an owner of a racing-stable. With the tail of his eye Checkers read what he was writing. It was a telegram to some one in St. Louis, and ran: "Stand a tap on the mare to-day. She can't lose." Checkers' heart was in his mouth. Instantly his resolution was taken. Out into the street he followed Brown. With the furtive care of a Hackshaw he shadowed him in and out of hotels and saloons, until about noon they brought up at a restaurant, where Checkers modestly seated himself at a table behind Brown and ordered a light repast. But Brown was hungry, and Checkers had ample time to think the thing over. "I 'm in luck at last," he soliloquized. "Stand a tap on the mare! His friend will play it in the foreign-book at East St. Louis and he 'll play it at the track. It must be a 'hot one'--I wonder what the odds will be. Well, I 'll keep this can 't-shake-me glide on my feet till I see what he plays, and then 'get down' on it myself. I 'll put up the gold-piece, and stand to either lose it or make a stake for myself. Somehow I 'd feel better to have it go in one last effort to make a killin' than to spend it a quarter at a time on sandwiches and cigarettes. To-night I 'll either be able to write to Pert that my luck has turned, or I 'll know the worst, and that 's some comfort. Ah, Brown 's paying his bill at last." The summer meeting at Washington Park, with large purses and high-class horses, was over and gone. But there were other tracks where racing was carried on all the fall and most of the winter; gambling-hells, pure and simple, or rather, purely and simply gambling-hells, which the Legislature has since effectively closed. In the betting-ring of one of these, that afternoon, Checkers threaded his way through the crowd after Brown. The programme showed that Brown had an entry in the last race--Remorse, an aged selling-plater. Checkers remembered the horse as one that had shown considerable speed as a three-year-old. He glanced at the programme again: Remorse, by Gambler, dam Sweetheart. Was it an omen? Remorse would certainly follow if he gambled away the keepsake which his sweetheart had given him. But wouldn't an equally poignant regret possess him if after this providential tip he failed to play the horse and she won? He felt that it would. The fourth race was on, and the last was approaching. Brown stood at the edge of the ring, his hands in his pockets, smoking idly. The official results of the fourth were announced, and the bookmakers tacked up the entries for the last. Still, Brown seemed nonchalant.
