as a soft and sudden breeze stirred the curtains. “If they ain’t in pretty quick they’ll get wet. There’s somebody now!” A tramp of feet clumped on the porch, the door was thrown open and a young man limped in. He was tall, almost as tall as Dick Colton, but much slenderer, and extremely dark. Despite his unsteady gait, he bore himself with an inimitably buoyant and jocund carriage.
