Dr. Watson and Sir Henry found out, that the night before Mrs. Barrymore was crying. But they didn`t knew the reason. The telegramm which Holmes sent to Mr. Barrymore, was not picked form him, but it was picked up from Mrs. Barrymore, the postman said to Dr. Watson. His wife wife said at this time, that he was up in the attic, and so she answered and not her husband. And so on Dr. Watson met Mr. Stapleton in the moor. They were taking about the legend from the hound of the Baskervilles and about Sir Charles. They saw how a pony drowend in the moor. And also a long, deep mouring of sadness. Dr. Watson met Mr. Stapletons sister, which tought that he was Sir Henry, and she said he should disappear from the moor.
