At first glance he could only barely distinguish the outlines of her figure, dimly discernable against the dark background of the upholstery, but, as his eyes accustomed themselves to the faint light, her features also became dimly visible—­enough so, at least, to convince him that she was young.  Neither spoke for some moments, while the automobile gathered speed, and West had an uncomfortable feeling that the lady was watching him with great intentness.  Slightly embarrassed, and uncertain as to his best course of action, the young man remained silent, his eyes on the burly back of the chauffeur, revealed through the front glass.  He could only quietly await her explanation of this strange situation.  The delay was not a long one.  She laughed, nervously perhaps, yet with a sense of humour at the awkward position.

“Quite melodramatic, is it not, Captain West?” she asked, in a decidedly pleasant voice.  “I trust it appeals thoroughly to that disposition for adventure of which you wrote.  I assure you I have arranged the details to the best of my ability.”

“Nothing more could be desired, I am sure,” he confessed, surprised at her tone, and glancing toward her.  “I certainly am left completely in the dark, unable even to clearly distinguish my mysterious companion in adventure.”

“And there really is no longer any occasion for such concealment.”  She lifted the heavy curtain beside her, permitting the grey light to rest upon her face.  “I preferred not to be seen at the park for obvious reasons; but here, alone with you, such precaution is quite unnecessary.  We are to be either friends, or enemies, so frankness is the best course.”

He saw the face of a young woman of twenty-four, or five, with dark eyes and hair, her cheeks flushed with health and excitement, her lips smiling.  It was a face of unusual attractiveness, not regular, perhaps, in any of its features, yet filled with character, and glowing with life.  It was to him a totally unfamiliar countenance, but one which as instantly awakened his interest.  He liked the girl, and believed in her.

“I can only thank you,” he said, rather lamely.  “Although I do not understand now how we could ever become enemies.  Surely, that is not a threat?”

“Oh, no, it is far too true.  You have yet to learn what I require.  Yet that was very nicely said.  I take it to mean your first impression of me is not unfavourable?”

“Very far from it.  I am already deeply interested in my task.  If I lacked an incentive before, you have furnished it.  I am only too glad I was the fortunate volunteer.”

She laughed again softly, her eyes still on his face.

“Really, I had not anticipated such a sincere compliment.  No doubt you learned these delightful speeches in France,” she answered, a very faint tinge of sarcasm in the words.  “However, this is a very serious matter, Captain West, and really has nothing to do with my personal appearance.  I am, of course, being a woman, glad that I please you, but we must consider this particular affair from an entirely different standpoint.  I am seeking neither flirtation nor compliment; merely a trustworthy agent.  First of all, it is necessary that you comprehend this.”
