Welton Keynes sees a job as male secretary advertised by Miss Ferriby of The Lawns in London. On the way to the interview he is warned by neighbours that several young men employed in that house have disappeared. Ignoring the advice, he takes the job, but it is not long before Welton Keynes realizes something strange and dangerous is taking place in Miss Ferriby's house. There are her mysterious clients, wealthy men and women coming to attend her séances. Although the large house is well kept, there seem to be no servants apart from the footman who is strangely out of place in that role. Welton decides to explore behind the locked doors. What he discovers signs his death warrant, unless ...
This is an old fashioned story of murder, robbery and séances, with a touch of romance. It was written in 1910 when political correctness in fiction was not even on the horizon, and the main villain was often physically disabled or disfigured (as here) to make him or her appear more villainous. Note that the physical descriptions of the characters are from the original book. It's how writers of popular fiction generally wrote, and what their readers read. Be warned: Miss Ferriby will carry on living in the some dark corner of your mind long after you have finished the story.
