The adventure of the stolen human skull : the spinsters of Barker Street no. 2

"Baroness Sofiya Konstantinova Babayevna, known for her work in the field of Theosophy, famously claimed to own a genuine Human skull, the only one in existence. My dear friend Miss Monette LeRoi, the consulting detective, did not learn about this curiosity until the day it was stolen." From "The Reminiscences of Tiffany Teckel, M.D.", published intermittently between 1892 and 1914. It's a world where some beasts think and talk like in a fable... Where humanity is only a fable... and Queen Victoria of England is a chicken... Two spinsters sharing an apartment on Barker Street fight crime.
