Murder by Gaslight

Arthur Conan Doyle

"You have been in Afghanistan, I perceive." With these few words, Holmes astonishes Watson for the first, if not the last, time on the occasion of their meeting. A mysterious corpse without wounds and a bloody design on the wall nearby inaugurates their first case of detection.
This is the beginning of Sherlock Holmes' many adventures. It is also available as a graphic novel, video, audio, or as part of most Sherlock Holmes collections.

"The eldest son of Queen Victoria, Bertie will one day be King Edward VII. For the moment, though, his primary responsibility is to enjoy himself, a task at which he excels - bedding society beauties, tormenting his long-suffering wife, and taking his royal bulk off to other people's country estates, there to shoot things, eat enormous meals, and pinch the serving maids. It is at just such an estate that the story unfolds, though this is no ordinary shooting-party, and with a killer afoot, the glittering guest-list is dwindling rapidly. Bertie greets the murders with some delight, as they allow him to exercise his passion for amateur sleuthing (a task at which he doesn't particularly excel)."
M.J. Trow

Mark Frost

Young Arthur Conan Doyle battles the wicked forces of the Dark Brotherhood to defend the Crown. He is aided by Queen Victoria's best agent, Jack Sparks, a man of keen wit who bears a great resemblance to Doyle's later creation, Sherlock Holmes. Demons, zombies, and the Dweller on the Threshold make this a more pungently purple mystery than many in Victoriana.

Amanda Quick

Plagued by rumors that she poisoned her fiancé, Lucinda Bromley lives on the fringes of polite Victorian London society, tending her beloved plants--and occasionally consulting on a murder investigation. For the notorious botanist can detect almost any type of poison, especially those derived from plants. But the murder of a lord has shaken Lucinda: at the scene, she picks up traces of a toxin from a very rare species. So rare, in fact, that only one specimen exists in England--and it was stolen from her conservatory last month. To keep her name out of the inquest and to find the murderer, Lucinda hires fellow Arcane Society member Caleb Jones, who runs a psychical investigation agency. But as desire blooms between Caleb and Lucinda, they are drawn into the dark heart of a deadly conspiracy that can be traced to the early days of the Arcane Society. (From the publisher's description)
