"It has not flowered yet?"

"No. But the buds—huge, smooth, egg-shaped things—seem on the point of bursting at any moment. We call it the 'Mystery,' and it is my special care. Mr. Saunderson has shown me how to attend to its simple needs, and if it proves to be a new species—which is almost certain—he is going to exhibit it, and name it after me! Shall you be proud of having an orchid named after—"

"After my wife?" Cairn concluded, seizing her hands. "I could never be more proud of you than I am already...."


CHAPTER XXIII

THE FACE IN THE ORCHID-HOUSE

Dr. Cairn walked to the window, with its old-fashioned leaded panes. A lamp stood by the bedside, and he had tilted the shade so that it shone upon the pale face of the patient—Myra Duquesne.

Two days had wrought a dreadful change in her. She lay with closed eyes, and sunken face upon which ominous shadows played. Her respiration was imperceptible. The reputation of Dr. Bruce Cairn was a well deserved one, but this case puzzled him. He knew that Myra Duquesne was dying before his eyes; he could still see the agonised face of his son, Robert, who at that moment was waiting, filled with intolerable suspense, downstairs in Mr. Saunderson's study; but, withal, he was helpless. He looked out from the rose-entwined casement across the shrubbery, to where the moonlight glittered among the trees.

Those were the orchid-houses; and with his back to the bed, Dr. Cairn stood for long, thoughtfully watching the distant gleams of reflected light. Craig Fenton and Sir Elwin Groves, with whom he had been consulting, were but just gone. The nature of Myra Duquesne's illness had utterly puzzled them, and they had left, mystified.
