    That day at dinner time, the housekeeper said to Henry with hesitation, "Sir, you are so good to us. Therefore, I feel I should tell you one thing that is correlated with the death of Sir Charles, your uncle. Because it is concerning his reputation, I have never told anybody so far." Watson and Henry stood up at once and asked him to speak out.
    "I know Sir Charles was waiting for a woman at the small gate before he died," remarked the housekeeper, "That morning he received a letter, written by a woman. Several weeks ago, my wife found the letter burnt incompletely when cleaning up his study. It said, "Please make sure to burn the letter and meet me at the gate of the fence. L. L." Who was the woman? Watson went to ask Doctor Mortimer, who went to him for help initially. Thinking for a moment, the doctor said, "A woman named Laura had once been helped by Sir Charles. She had some contacts with Sir Charles. Could it be written by her?" Watson found Laura. She admitted that she did write the letter in order to obtain some financial assistance. But she said she did not go to meet him that night.
