"No; nor ever will," was the brief response, and Lloyd's face grew stern with the pain of other years. "As I told you, Bob, I was detailed here to solve a very serious problem for our government," he resumed, after a slight pause. "Baker has rounded up and arrested all persons suspected of corresponding with the rebels, and sent some to Old Capitol Prison, and others through the lines to Richmond, where they can do us no harm. Most of these spies gave themselves away by their secesh talk, or by boasting of their ability to run the blockade.
"But information of our armies' intended movements is still being carried out of Washington right under Baker's nose. It is imperative that this leak be stopped at once, or the Union forces may suffer another Bull Run. Baker and the provost marshal of the district have tried every means in their power to learn the methods and the identity of this spy, but so far without success."
"But have you found no trace in your search?" inquired Goddard eagerly.
"Until to-day I had only a theory; now I have a clue, a faint one, but——" Lloyd paused and glanced about the room to see that he was not overheard. They had the place to themselves, save for their waiter, Sam, who was busy resetting a table in the opposite corner. "I have told you, Bob, how I came to get this wound"—Lloyd touched his temple—"when on my way to Poolesville." Goddard nodded assent. "But I did not tell you that before the supposed trooper made good his escape his hat was knocked off and Symonds saw that the spy was a woman."
"A woman!" Goddard nearly dropped his cigar in his astonishment. "How did he find that out?"
"Her hair fell down her back when her hat was knocked off."
Goddard stared at his companion. "Well, I'll be—blessed!" he muttered.
"I have been looking for such a woman for some time, and until to-day without success," declared Lloyd calmly.
"Did she by chance leave any trace, any clues, behind her in her flight?"
"One." Lloyd pulled out his leather wallet. "On examining the hat, which he picked up on his return to where I was lying unconscious, Symonds found these hairs adhering to the lining. He put them in an envelope and brought them to me at the hospital." Lloyd drew out a small paper, which he opened with care. "Have you ever seen hair of that color before?"
