Some Murderers in the Holmes Canon Quiz

Answer: Sherlock Holmes

An easy one to start with. In "The Adventure of The Final Problem", Holmes used baritsu to throw Moriarty to his death in the Reichenbach Falls.

Answer: Tonga

Tonga was the Andaman Islander associate of Jonathan Small, who Holmes and Watson shot in "The Sign of Four".

Answer: The Ku Klux Klan

This was in "The Adventure of the Five Orange Pips". The Scowrers were in "The Valley of Fear".

Answer: Colonel Sebastian Moran

In "The Adventure of the Empty House", the old associate of Moriarty used "the famous air-gun of Von Herder" to kill Adair, and even fired it through the window of Baker Street.

Answer: Mrs Hudson's terrier

In "The Sussex Vampire", Robert Ferguson's son, Jack, did poison their spaniel, Carlo, but it survived. In "A Study in Scarlet", Holmes poisoned and killed "the landlady's terrier", to test a theory. (It was, to be fair, ill). In "The Adventure of The Copper Beeches", the mastiff, also called Carlo, had his brains shot out by Dr Watson.

In "Silver Blaze", the horse of the same name killed its trainer, John Straker.

Answer: Hugo Oberstein

From "The Adventure of The Bruce-Partington Plans". Sir James Walter died after discovering that his brother, Col. Valentine Walter, had sold government secrets to Hugo Oberstein. Walter helped dispose of the body in an intriguing manner, but did not murder West. Oberstein did this with a blow to the head. Eduardo Lucas was a foreign agent from a different story, "The Adventure of The Second Stain".

Answer: Mr John Turner

In "The Boscombe Valley Mystery", it certainly seemed black against James McCarthy, the murdered man's son. Holmes, however, managed to extract a confession from John Turner, which he kept a secret, after securing young James' release. It is thought that he and Miss Turner later married, and never discovered the truth of their fathers' histories. That is, unless they read "The Strand" magazine!

Answer: Mrs Gibson

In "The Problem of Thor Bridge", the wronged wife of Neil Gibson, the Gold King and ex-American senator, devised an ingenious method of suicide.

Answer: Cyanea Capillata

"The Adventure of the Lion's Mane" occurred after Holmes had retired to keep bees. Radix pedis diaboli gives it's name to "The Adventure of the Devil's Foot".

Answer: Dr Grimesby Roylott

From one of the best, and most famous of Holmes' cases, "The Adventure of the Speckled Band", Dr Roylott used a swamp adder to kill Julia Stoner. Her twin sister, Helen, would have met the same fate, but for the intervention of Holmes & Watson - in a very vivid story.
Joseph Stangerson is from "A Study in Scarlet".
