It was my turn now to exhibit surprise. "No. 28!" I exclaimed. "Who lives there?" "I don't know. Mrs. Dowsett and Letitia went to Margate by an early train on Saturday morning, before I was awake, and my guardian has gone there to see them. I should have proposed to go with him had it not been for my determination not to leave London till this dreadful mystery was cleared up; and then there was the promise you made me give you last night, that I should remain here all the day till you came to see me." "When did your guardian go to Margate?" I asked. "He has gone from Victoria," replied Carton, glancing at a marble clock on the mantelshelf, "by the Granville train. It starts at fifteen minutes past three." I also glanced at the clock. It was just half-past three, a quarter of an hour past the time! CHAPTER XXV. WE FOLLOW IN PURSUIT. Carton, noticing my discomposure, inquired if there was anything wrong. I answered, yes; I was afraid there was something very wrong. "In connection with the fate of my poor girl?" he asked. "Yes," I replied, "in connection with her fate." "Great heavens!" he cried. "You surely do not suspect that my guardian is mixed up with it?" "I am of the opinion," I answered guardedly, "that he may be able to throw some light on it. Mr. Carton, ask me no further questions, or you may seriously hamper me. Have you a time-table in the house? No? Then we must obtain one immediately. It is my purpose to follow your guardian to Margate by the quickest and earliest train. I give you five minutes to get ready." Greatly excited, he darted from the room, and in half the time I had named returned, with a small bag, into which he had thrust a few articles of clothing. During his absence I said to Devlin, "You will accompany us?" "My dear sir," he replied, "I will go with you to the ends of the earth. I shall greatly enjoy this pursuit; the vigour and spirit you are putting into it are worthy of the highest admiration."
