I would just like to recommend a great post-eppy fic for "The Reichenbach Fall".
It's
theteej2's
A Mutual Grief, which basically focuses on John and Lestrade after Sherlock's "death" and the way they begin to repair their friendship. It also features Anne Lestrade, who was first introduced in
A Dish Served Cold, a deliciously long story full of adventure, Lestrade angst and a bit of hurt/comfort for good measure. This is followed by
That Christmas Eve, which provides a clever explanation for why Sherlock thought Lestrade's wife was having an affair. *g*
