"Another interruption stopped her ... A hesitating step crossed the threshold" 278 THE LOST DESPATCH CHAPTER I THE PIGEON'S FLIGHT It was bitterly cold that December night, 1864, and the wind sighed dismally through the Maryland woods. The moon, temporarily obscured by heavy clouds, gave some light now and then, which but served to make the succeeding darkness more intense. Suddenly the silence was broken by the clatter of galloping hoofs, and two riders, leaving the highway, rode into the woods on their left. The shorter of the two men muttered an oath as his horse stumbled over the uneven ground. "Take care, Symonds," said his companion quickly, and he ducked his head to avoid the bare branches of a huge tree. "How near are we now to Poolesville?" "About seven miles by the road," was the gruff reply; "but this short cut will soon bring us there. And none too soon," he added, glancing at their weary horses. "Still, Captain Lloyd, we have done a good night's work." "I think Colonel Baker will be satisfied," agreed Lloyd. "And friend Schmidt, now that he sees the game is up, will probably turn state's evidence." Lloyd shook his head. "I doubt if Schmidt can tell us much. He is too leaky a vessel for a clever spy to trust with valuable information." "But," objected Symonds, "that is a very important paper you found in his possession to-night." "True; but that paper does not furnish us with any clue as to the identity of the spy in Washington. Schmidt is simply a go-between like many other sutlers. Probably that paper passed through three or four hands before it was given to him to carry between the lines." "Well, there is one thing certain; Baker will make Schmidt talk if any man can," declared Symonds. "May I ask, Captain, why we are headed for Poolesville?" "Because I am looking for the man higher up. I expect to get some trace of the spy's identity in or around Poolesville." "You may," acknowledged the Secret Service agent doubtfully; "and again you may not. Poolesville used to be called the 'rebs' post-office,' and they do say that word of every contemplated movement of McClellan's army was sent through that village to Leesburg by the 'grape-vine telegraph.'" "Yes, I know," was the brief reply. The two men spoke in lowered tones as they made what speed they could among the trees. "By the way, Symonds, has it ever been discovered who it was delayed the despatch from Burnside, asking for the pontoon bridges?" "No, never a trace, worse luck; but do you know," drawing his horse closer to his companion, "I think that and the Allen disaster were accomplished by one and the same person." "Those two and a good many others we haven't yet heard of," agreed Lloyd. "In fact, it was to trace this particular unknown that I was recalled from service at the front by Pinkerton, and detailed to join the branch of the Secret Service under Colonel Baker."
