The modest bookshelves of my childhood home supported various copies of every Sherlock Holmes publication my father could lay his hands on. He developed an encyclopedic knowledge of Sir Arthur Conan Doyle's Holmes oeuvre, and continued for many years to insist (ironically) that the detective not only had lived but was alive and well (if ancient) in Dover, England, keeping bees.
Despite that almost constant exposure to Holmes-related literature and memorabilia, I never read many of the stories myself. I primarily became familiar with the character through TV and by listening to my father's recording of the old radio programs. Recently, while deciding what books to take on our brief excursion to Orcas Island, I grabbed The Adventures and Memoirs of Sherlock Holmes from the shelf of our local library.
My experience reading all 40 or so stories in the collection over the span of a few days was not unlike how I felt after watching a marathon session of The Sopranos on DVD: I was exhausted and concluded that the episodes are clearly meant to be consumed with a significant break in between.
That is not to say that I didn't enjoy them, but only that the formula became rather tiresomely repetitive when taken altogether, and I found myself skimming. It would have been a different experience if I were a Victorian-era gentleman who had to wait a month for the next issue of The Strand in order to get more Holmes action, and I'm sure that Conan Doyle was mindful of that when he wrote the stories.
One significant trope jumped out at me, however, that I was unprepared for and that I might not have picked up on had I not read them all in such a short period of time.
