Abercrombie Smith, Edward Bellingham and William Monkhouse Lee are three students at Oxford University, sharing adjacent lodgings. When people against whom Bellingham holds a grudge are attacked, Smith starts to investigate. Is Bellingham innocent? But what are the strange noises coming from his room when he is not home? This short gothic horror story first published in 1892 is a bit outside the usual haunts of Conan Doyle and has been compared to the writings of Edgar Allan Poe and H. Rider Haggard. - Summary by Availle
