THERE was more than a fair sprinkling of customers in the Happy Heart Saloon. Tom Dowling of the 88, Racey Dawson of the Cross-in-a-box, and Telescope Laguerre of the Bar S were draped against the bar earnestly engaged in lowering the tide in a bottle of Old Crow. Four of the Hogpen outfit and a skinny gentleman hailing from the Double Diamond A were absorbed in draw at the table in the far corner. At the other table, near the door, sat Johnny Ramsay of the Cross-in-a-box. He was a tall, lean young man, with a cool, sardonic gray eye and a sunburned face.
