Miss Kerr began to turn purple.

“In the lavatory, Doctor.”

“What time did you get into the Clinic this morning, Miss Kerr?”

She turned her defiant eyes upon Cub Sterling and struck:

“At four sharp. The night superintendent had called me at three-thirty and told me. I came over immediately. You were still with Dr. MacArthur, I believe.”

Again his “Thank you” cut her down.

Dr. MacArthur realized she was useless, so he said:

“Thank you, Miss Kerr. You have been a great help. Of course I do not have to ask a person of your integrity to realize the necessity of silence.”

Princeton took his cue and opened the door.

Miss Kerr rose majestically and smiled inclusively.
