We had been moving all this time in the direction of the station and had now reached the foot of the platform. Pausing, she cast a last look up the bank. The trees were thick and hid from our view the Ocumpaugh mansion, but in imagination she beheld the mother moaning over that little shoe. "I shall never return there," she muttered; "why do I hesitate so to speak!" Then in a burst, as I watched her in growing excitement: "She--Mrs. Ocumpaugh--begged me not to tell what she believed had nothing to do with our Gwendolen's loss. But I can not keep silence. This proof of a conspiracy against herself certainly relieves me from any promise I may have made her. Mr. Trevitt, I am positive that I know who carried off Gwendolen." This was becoming interesting, intensely interesting to me. Glancing about and noting that the group down at the water-edge had become absorbed again in renewed efforts toward further discoveries, I beckoned her to follow me into the station. It was but a step, but it gave me time to think. What was I encouraging this young girl to do? To reveal to _me_, who had no claim upon her but that of friendship, a secret which had not been given to the police? True, it might not be worth much, but it was also true that it might be worth a great deal. Did she know how much? I wanted money--few wanted it more--but I felt that I could not listen to her story till I had fairly settled this point. I therefore hastened to interpose a remark: "Miss Graham, you are good enough to offer to reveal some fact hitherto concealed. Do you do this because you have no closer friend than myself, or because you do not know what such knowledge may be worth to the person you give it to--in money, I mean?" "In money? I am not thinking of money," was her amazed reply; "I am thinking of Gwendolen." "I understand, but you should think of the practical results as well. Have you not heard of the enormous reward offered by Mr. Ocumpaugh?" "No; I--" "Five thousand dollars for information; and fifty thousand to the one who will bring her back within the week unharmed. Mr. Ocumpaugh cabled to that effect yesterday."
