As he slowly smoothed out the check and stub, pen poised, Keen was saying: "Of course, we should succeed sooner or later--if we took up your case. We might succeed to-morrow--to-day. That would mean a large profit for us. But we might not succeed to-day, or next month, or even next year. That would leave us little or no profit; and, as it is our custom to go on until we do succeed, no matter how long it may require, you see, Mr. Gatewood, I should be taking all sorts of chances. It might even cost us double your retainer before we found her--" "Her? How did--why do you say 'her'?" "Am I wrong?" asked Keen, smiling. "No--you are right." The Tracer of Lost Persons sank into abstraction again. Gatewood waited, hoping that his case might be declined, yet ready to face any music started at his own request. "She is young," mused Keen aloud, "very beautiful and accomplished. Is she wealthy?" He looked up mildly. Gatewood said: "I don't know--the truth is I don't care--" And stopped. "O-ho!" mused Keen slowly. "I--think--I understand. Am I wrong, Mr. Gatewood, in surmising that this young lady whom you seek is, in your eyes, very--I may say ideally gifted?"

I fancy she might be, perhaps, an inch or two under your height?" "Just about that. Her hands should be--are beautiful--" "Exactly. The ensemble is most vividly portrayed, Mr. Gatewood; and--you have intimated that her lack of fortune--er--we might almost say her pecuniary distress--is more than compensated for by her accomplishments, character, and very unusual beauty. . . . Did I so understand you, Mr. Gatewood?" "That's what I meant, anyhow," he said, flushing up. "You did mean it?" "I did: I do." "Then we take your case, Mr. Gatewood. . . . No haste about the check, my dear sir--pray consider us at your service." But Gatewood doggedly filled in the check and handed it to the Tracer of Lost Persons. "I wish you happiness," said the older man in a low voice. "The lady you describe exists; it is for us to discover her." "Thank you," stammered Gatewood, astounded.
