In one great wave the blood rushed over her face, and she held out her hand.

"Oh, Dr Dudley, forgive me!" she said.

"I want to," he said quite simply. "I have been far more to blame than you, but that is nothing. Tell me about it. Did our friendship mean nothing to you?—had I no claim upon your candour? Don't look out of the window; look me in the face."

"Dr Dudley," she said, "you are so quick, so clever, did you not see? My cousin had asked me not to say that I was a medical student, and I had promised faithfully to do as she wished.

"Your reading is the correct one," said Dudley gravely. "You are perfectly right."

But his own confession was still to make, and he was determined not to make it by halves.

"In the course of our acquaintance, Miss Maclean," he began somewhat stiltedly, "you have known me in the three-fold capacity of snob, fool, and child."
