Ella turned on her.

"You knew it was Ballingall?--How did you know it was Ballingall? It seems to me that you know everything."

"Miss Brodie," observed Bruce Graham, "very naturally draws her own conclusions. The sight of him turned me into a drivelling idiot. In the confusion of my mind his appearance on the scene at that particular moment seemed nothing short of supernatural. I felt as if I had been guilty of some act of treachery towards him, and as if he had sprung from goodness alone knew where to catch me in the very act. I blundered through the gate, knocked at the door and almost forced my way into the house."

"You did almost force your way into the house."

Madge's tone was grim.

"I'm afraid I did--and, being in, I blurted out some nonsense about being in search of music lessons, and generally misbehaved myself all round. As a climax, just as I was about to put an end to my intrusion, I saw Ballingall staring at me through the window. I would not have encountered him then for all the hidden hoards the world contains. I entreated Miss Brodie--to permit me to make my escape through the back door--and she did."

"Yes, and insulted you as you went."

Graham rose from his seat.

"You behaved to me, Miss Brodie, infinitely better than I deserved. You would have been perfectly justified in summoning a policeman, and giving me into charge. I can only thank you for your forbearance. I assure you of my most extreme penitence. And while I cannot expect that you will forgive me at once----"

"But I do forgive you."
