John Watson: [upon first seeing Baker Street] Well this is a prime spot. Must be expensive.
Sherlock Holmes: Mrs. Hudson, the landlady is giving me a special deal. She owes me a favor. A few years back her husband got himself sentenced to death in Florida. I was able to help out.
John Watson: You stopped her husband from being executed?
Sherlock Holmes: Oh, no. I ensured it.
