The “Gloria Scott”, one of the 56 Sherlock Holmes short stories written by British author Sir Arthur Conan Doyle, is one of 12 stories in the cycle collected as "The Memoirs of Sherlock Holmes".  It is chronologically the earliest case in Sherlock Holmes canon.  This story is related mainly by Holmes rather than Watson, and is the first case to which Holmes applied his powers of deduction, having treated it as a mere hobby until this time.  This is one of the two Sherlock Holmes stories in which a protagonist is haunted by an old acquaintance for an old crime.  The other is "The Boscombe Valley Mystery." Sherlock Holmes (a.k.a.

"The Adventure of the Musgrave Ritual" is a short story by Arthur Conan Doyle, featuring his fictional detective Sherlock Holmes.  The story was originally published in "Strand Magazine" in 1893, and was collected later in "The Memoirs of Sherlock Holmes".  Unlike the majority of Holmes stories, the main narrator is not Doctor Watson, but Sherlock Holmes himself.

It is one of the earliest recorded cases investigated by Holmes, and establishes his problem solving skills.

Professor James Moriarty is a fictional character and the main antagonist in some of the Sherlock Holmes stories written by Sir Arthur Conan Doyle.  Moriarty is a criminal mastermind whom Holmes describes as the "Napoleon of crime".  Doyle lifted the phrase from a Scotland Yard inspector who was referring to Adam Worth, a real-life criminal mastermind and one of the individuals upon whom the character of Moriarty was based.  The character was introduced primarily as a narrative device to enable Doyle to kill Sherlock Holmes, and only featured in two of the Sherlock Holmes stories.  However, in many adaptations, he has been given a greater prominence and treated as Holmes' archenemy.
