"But we have come back to save her," she exclaimed quickly. "This is no time for despair, Charlie; we have a greater power given to us than you imagine. We shall work in secret--you and I--and we shall succeed. See now"--she held my hands, and looked into my eyes, and smiled encouragingly--"you are calmer already than you have been. It seems to me that the best thing we can do is to get to London at the earliest possible moment. Barbara has been taken there--the boy has gone there; this man Murray Olivant will inevitably follow. You know where he is to be found, and we may be able to trace the boy. There is nothing to be frightened of yet, Charlie; we will fight together, because we understand so much more than these other people do." She was so wise and calm that she seemed to give me wisdom too. I presently found myself walking beside her back towards the town; it was her intention to shelter me for the night at that tiny cottage where she lived near Hammerstone Market. She had a key to the place, and we crept in silently; she gave me some poor food she had there, and insisted that I should stretch my weary limbs on an old couch in the sitting-room for the remainder of the night. I slept heavily, and long before dawn, as it seemed, I found her standing beside me, gently waking me. She had prepared some steaming hot coffee, and I drank it gratefully, while she sat beside me and told me what I was to do. "This man Murray Olivant still feels that you may be useful to him," she said; "in any case, you know too much about his plans to be lightly thrown aside. I have money here that will take you to London; you will go to those rooms where Fanshawe first took you, and you will wait there for Olivant. Do you understand?" I said that I did, and that I would do all she suggested. "Two things you have to remember," went on the calm voice. "The first, that the boy must be prevented, at the present time at least, from meeting Olivant; I shudder to think what might happen if they met now. Persuade Olivant to get away--to hide--anything. The second is to get hold of poor Barbara, and to bring her back to her father, if by any chance we do not find young Millard. It may happen that, if Olivant is frightened of what may befall him if the boy finds him, he may throw up the game, and get out of the way; then our course is clear. But in any case, Charlie, we must not travel together. You will go first, and I will come afterwards; we can arrange some place in which to meet in London." She knew as little about London as I did; therefore she chose the first public place she could think of for our later meeting. I was to find her on one of the seats on the north side of Trafalgar Square, just under the terrace; it was the only place we could think of in the hurry of the moment.
