"By the way," he remarked, as I stood watching him with an uncompromising air, "I have forgotten to mention the name of the town in which these disappearances have occurred. It is called X., and it is to be found on one of the spurs of the Berkshire Hills." And, being by this time at the door, he bowed himself out with all the insinuating suavity which distinguishes him at certain critical moments. The old fox was so sure of his triumph that he did not wait to witness it. He knew--how, it is easy enough for me to understand now--that X. was a place I had often threatened to visit. The family of one of my dearest friends lived there, the children of Althea Knollys. She had been my chum at school, and when she died I had promised myself not to let many months go by without making the acquaintance of her children. Alas! I had allowed years to elapse. III I SUCCUMB That night the tempter had his own way with me. Without much difficulty he persuaded me that my neglect of Althea Burroughs' children was without any excuse; that what had been my duty toward them when I knew them to be left motherless and alone, had become an imperative demand upon me now that the town in which they lived had become overshadowed by a mystery which could not but affect the comfort and happiness of all its inhabitants. I could not wait a day. I recalled all that I had heard of poor Althea's short and none too happy marriage, and immediately felt such a burning desire to see if her dainty but spirited beauty--how well I remembered it--had been repeated in her daughters, that I found myself packing my trunk before I knew it. I had not been from home for a long time--all the more reason why I should have a change now--and when I notified Mrs. Randolph and the servants of my intention of leaving on the early morning train, it created quite a sensation in the house. But I had the best of explanations to offer. I had been thinking of my dead friend, and my conscience would not let me neglect her dear and possibly unhappy progeny any longer. I had purposed many times to visit X., and now I was going to do it. When I come to a decision, it is usually suddenly, and I never rest after having once made up my mind. My sentiment went so far that I got down an old album and began hunting up the pictures I had brought away with me from boarding-school. Hers was among them, and I really did experience more or less compunction when I saw again the delicate yet daring features which had once had a very great influence over my mind. What a teasing sprite she was, yet what a will she had, and how strange it was that, having been so intimate as girls, we never knew anything of each other as women! Had it been her fault or mine? Was her marriage to blame for it or my spinsterhood? Difficult to tell then, impossible to tell now. I would not even think of it again, save as a warning. Nothing must stand between me and her children now that my attention has been called to them again.
