Sherlock Holmes walked into a book store, somewhere in America, one day after the Fall, subconsciously gravitating towards the mystery section. Stopping in front of one of the shelves, he closed his eyes and grabbed a random book.

The Beekeeper's Apprentice by Laurie R. King. The title alone intrigued Sherlock… and then he looked at the synopsis of the novel.

Something about this book irritated the detective, but he found he couldn't stop himself for paying for it.
