play would be pigeon-holed indefinitely. Price's eyes were starting from his head, but he kept his tongue between his teeth.) Mr. Yelverton seemed amused. "I guess I may be able to manage that," he said, "if one or both of those keys are still in our hands, as I believe they are. If I do the trick for you I'll expect a box for the play on the first night, eh?" "It's a bargain, isn't it, Carr?" said I. The dazed Price assented.
