Your staff or you if anything goes wrong.” “I doubt if anyone could do much to me,” said Professor Glastonberry, “but it’s true I wouldn’t want my cleaners or my caretaker blamed.” “The trouble is,” said Maia, looking up at him, “I haven’t actually stolen anything before.” “There is always a first time,” said the professor cheerfully. “The spare keys are hanging on that hook over there. And I’m going out in half an hour to have my lunch.””
