On the Holmes AdventuresBy Ralph Edwards
The Hounds of the Internet is the longest established online recognized scion society of the Baker Street Irregulars, organized for the discussion of Sherlock Holmes and kindred topics. It has been in existence since 1992. The format of the Hounds is to discuss one story each week in the order published in Baring Gould's, The Annotated Sherlock Holmes, except that the “Adventure of the Blue Carbuncle” is always discussed at Christmas.
One of the Hounds, posts some devilishly hard and interesting "quiz" questions for each tale. Click below for the fun. However, there are not queeries for HOUN, VALL, and SIGN.
