Holmes raises an eyebrow and has another bite of soup. He isn't sure he's quite eager to thank his brother for setting him up with a permissive housekeeper; of course this is ideal, but it is a bit odd. And a bit... perfect.

"I believe that was her giving you permission to sleep in here," he points out. "My dear Watson, I believe our housekeeper suspects that we're homosexuals."
