Sherlock is an intricate show, to say the least. But among all the cases, the clues, the crime scenes and the curious motives, lies the biggest mystery of all: the man himself. In three short series, we've unravelled new layers of the character gradually; the man who nearly died gambling with his life in the first episode, developed into a man who risked everything to bring down Charles Augustus Magnussen, and give his best friends a normal life. There were hints at the plot twists that were to come, but did we actually notice them? Steven Moffat's known for his timey-wimey, twisting arcs that span across multiple series; he ended a Doctor's reign by answering the questions raised in his first episode. But Sherlock is a different kettle of fish; the questions much more subtle, much more character-centric and actually, a lot of them don't matter all that much. They're just nuggets that reveal wonderful details about these characters that we love. Here are ten beautifully elegant uses of foreshadowing in Sherlock, that you might not have noticed before.
