“Sherlock” explores a crucial ten-minute scene from the episode “His Last Vow”, part of the TV show “SHERLOCK”. This book focuses on Sherlock Holmes’ distinct thinking method, known as the mind palace. Each part of the book mirrors different “rooms” in Sherlock’s mind.

Rather than sticking to a straight storyline, the book mixes things up. Readers need to follow numbers to piece together the story in chronological order, jumping from one section to another, just like Sherlock moves between rooms within the mind palace.
