A SHAPE IN THE MOOR

The following day, Barrymore told Watson some important information: “I have found a letter that a woman, a certain L.L. from Combee Tracey, wrote to sir Charles asking him to meet her that evening, the evening of his death”. Dr. Mortimer, who was with Watson that morning, seemed thoughtful: “there is a woman with the initials "L.L." living in Combee Tracey: Laura Lyons, the disgraced, disowned daughter of Mr. Frankland” he said. Watson decided to find Laura, he really needed to talk to her, so he went to Combee Tracey to look for her. When he finally found her, he asked all of his questions: “Did you know Sir Charles? Why didn’t you go to the appointment the night he died?”. Laura reluctantly admitted that she knew him and that she received financial assistance from him. She didn’t go to the appointment because she had found the help she needed from another source. 

While Watson was returning to Baskerville Hall, Mr. Frankland saw him and invited him for a drink. The reason for this strange invitation was that Mr. Frankland wanted to confide something to Watson: “One night I was observing the moor with my telescope and I saw a guy bringing food there, if you want I can tell you the exact spot”. Watson concludes that the guy must have been bringing the food to the man he saw that night with Sir Henry, therefore he went to the moor following Mr. Frankland’s indications. When he arrived there, he found a piece of paper with written: “Dr. Watson to Combee Tracey”, somebody must have been following him. He decided to wait for the mysterious man. After some hours, he heard the sound of someone approaching and then a familiar voice that was calling him.
