Sherlock: Miss Mackenzie, you’re in charge of pupil welfare, yet you left this place wide open last night! What are you? An idiot, a drunk, or a criminal?! Now quickly! Tell me!
Miss Mackenzie: All the doors and windows were properly bolted. No one, not even me, went into their room last night. You have to believe me.
Sherlock: I do. I just wanted you to speak quickly.
Sherlock: Miss Mackenzie will need to breathe into a bag now.
