"You would have me take out my Celtic soul and put in a Saxon one," he said. "Either my brain is too small or my heart is too big. But when may I call and pay my respects to Mrs. Grey? Will she be at home this afternoon?"

"She is at home now. Come into the morning-room. She will be glad to make your acquaintance."

They walked across the linoleum-paved hall. The Professor opened the door of the room, and walked in, followed by his friend. Mrs. Grey was sitting in a basket-chair by the window, light and fairy-like in a loose-flowing, pink morning gown. Seeing a visitor, she rose and swept towards them. The Professor heard a dull thud behind him. O'Brien had fallen back into a chair, with his hand pressed tight to his side.

"Jinny!" he gasped—"Jinny!"

Mrs. Grey stopped dead in her advance, and stared at him with a face from which every expression had been struck out, save one of astonishment and horror. Then with a sharp intaking of the breath she reeled, and would have fallen had the Professor not thrown his long, nervous arm round her.

"Try this sofa," said he.

She sank back among the cushions with the same white, cold, dead look upon her face. The Professor stood with his back to the empty fireplace and glanced from the one to the other.

"So, O'Brien," he said at last, "you have already made the acquaintance of my wife!"

"Your wife," cried his friend hoarsely. "She is no wife of yours. God help me, she is my wife."

The Professor stood rigidly upon the hearth-rug. His long, thin fingers were intertwined, and his head had sunk a little forward. His two companions had eyes only for each other.
