The Adventure of the Veiled Lodger (Unabridged)

"The Adventure of the Veiled Lodger" (1927), one of the 56 Sherlock Holmes short stories written by British author Sir Arthur Conan Doyle, is one of 12 stories in the cycle collected as The Case-Book of Sherlock Holmes.
Holmes is visited by Mrs. Merrilow, a landlady from South Brixton who has an unusual lodger who never shows her face. She saw it once accidentally and it was hideously mutilated. This woman, formerly very quiet, has recently taken to cursing in the night, shouting "Murder, murder!" and "You cruel beast! You monster!" Also, her health has taken a turn for the worse, and she is wasting away. Mrs. Merrilow has brought this case to Holmes's attention as her tenant, Mrs. Ronder, will not involve the clergy or the police in something that she would like to say. She has told her landlady to mention Abbas Parva, knowing that Holmes would understand the reference.
