In other words, Sir Arthur Conan Doyle's stories about Sherlock Holmes are canon – or if not part of some universal canon, certainly an ancestor to wide swaths of stories about detectives and companions, intelligent men with abrasive personalities, and applying insight instead of force to resolve crimes.
When I went to check for first sentences, I found the stories drew me in. The writing holds up.
What clues does this first sentence hold to the lasting appeal of Sherlock Holmes?
The Sign of the Four is the second story Conan Doyle wrote about Sherlock Holmes. So the name Sherlock Holmes would have attracted readers who enjoyed the first story, but would not yet have had the widespread recognition it has now. "Sherlock Holmes" is a distinctive name. Neither the first name nor the last name are common. Together, they are very likely to mean one specific person. The name sticks in the mind better than a more common name might, and by its oddness, suggests the character will also be particular.
There are other very specific details: "mantlepiece" – the shelf above a fireplace, "hypodermic syringe" – at the time, a fairly new piece of medical technology, "morocco case" – a fitted container covered in a specific style of leather. These details are like the clues that the mysteries will hinge on. They are precise, meaningful, and observant.
At the time of the book, no law forbade a private citizen from having a syringe and a bottle of narcotic. Some people had developed addictions. In the following sentences, John Watson, a doctor, worries about Holmes' use of the drug.
Reaching for a bottle and syringe, then, like now, showed that Sherlock Holmes had a flaw. He was a closely observed character with both outstanding skills and significant weakness.
I like the opposition here between "hypodermic syringe" and "neat morocco case." The syringe is dangerous, novel, and piercing. The case is tidy, traditional, made from animal skin, and enclosing. The tension between these items reflects the concern that the character who has them will harm himself. Wanting to see what happens creates a subtle hook. If I know the name "Sherlock Holmes," this sentence is also a promise that I will learn more about a character I like, and that there will be more close observations and exact details.
This sentence works on many levels.
