 I believe you're right. Daddy, Nurse Peters is here. Where? In his laboratory. The lights just come on in the upper room, in the window, see? Well, you wait in the carriage with Nurse Peters, and I'll go out and get him. Will you take me through the house, Paul? Yes, Mr. Utterson, certainly, sir. Come this way, sir. Thank you. Tell him it's urgent, Daddy.
