 Miss Utterson, I'm awfully sorry to trouble you at such an hour, but I'm at my wit's end. Do you happen to know where Dr. Jekyll is? Isn't he with you, Nurse Peters? Well, he had dinner here, but left early saying he had to be down to see a patient at ten o'clock. At ten o'clock? Well, I don't know anything about that. The clinic shuts at five o'clock. Dr. Jekyll wasn't expected down again till two o'clock tomorrow afternoon. Was there some special case he had to see about? Not that I know of.
