I Believe
What Sherlock says when he’s not getting caught in a lie and he’s trying to look cool. It’s like when your friend says they believe in you, but they just want you to let them borrow your lunch money.
Sherlock said, "I believe I’m not a fraud." I said, "I believe you’re still a fraud."
He said, "I believe I’m innocent." I said, "I believe you’re lying."
Sherlock said, "I believe I’m not a fake." I said, "I believe you’re a fake."
