The Experiences of a Lady Detective.

Though originally believed to have first been published in 1861, experts in the genre have determined that to be a 'ghost issue', with the first edition actually appearing in 1864 under the title The Revelations of a Lady Detective. After this came a 'reissue with the title The Experiences, which [the British Museum] dated as of 1884' (Ellery Queen, In the Queens' Parlor, p. 43). Sometimes attributed to William Stephens Hayward. Features Mrs. Paschal, one of the very first female detectives.

Queen writes, 'we found a reprint of Revelations of a Lady Detective--an obvious reissue of later vintage. And on glancing through this later volume a strange sight met our astonished eyes. While the front cover and the spine clearly gave the title as Revelations of a Lady Detective, the title page just as clearly read The Experiences of a Lady Detective...' (Parlor, p. 42).
