On the left of the altar was the cupboard wherein, no doubt, in past ages, the priest had kept his vestments. The oppressive odour which Dillon had first observed in the dining-room was very perceptible in the chapel; and as Dr. Kassimere opened the door of the cupboard and stepped within, an explanation of the presence of this deathly smell in the house occurred to Dillon's mind. The laboratory adjoined the Grange on this side; here was a private entrance known to, and used by, Dr. Kassimere alone. His surmise proved to be correct. Occasioning scarcely a sound, the secret door opened, and a fiery glow leapt out across the altar steps, accompanied by a wave of heated air laden with the nauseous, unnameable smell. Within the redly lighted doorway, Dr. Kassimere paused, and glanced at a watch which he wore upon his wrist. Then for a moment he disappeared, to reappear carrying a small squat bottle and a contrivance of wire and gauze the sight of which created in Dillon a sense of physical nausea. It was a chloroform-mask! Both he placed upon a vaguely seen table and again approached the door. Weakly, Dillon fell back, pressing himself, closely against the chapel wall, as the doctor, this time leaving the secret entrance open--with a purpose in view which the watcher shudderingly recognized--recrossed the chapel and went off, softly treading, in the direction of the library. All his courage, moral and physical, was called upon now, and knowing, by some intuition of love, what and whom he should find there, he stepped unsteadily into Dr. Kassimere's laboratory.... That there were horrors--monstrosities that may not be described, whose names may not be written--in the place, he realised, in some subconscious fashion; but--prone upon a low, metal couch of most curious workmanship lay Phryné, in her night-robe, still--white; perfect in her pale beauty as her namesake who posed for Praxiteles. Dillon reeled, steadied himself, and sank upon his knees by the couch. "Phryné!" he whispered, locking his arms about her--"my Phryné!..." Then he remembered the gauze mask and even detected the sickly, sweet smell of the anaesthetic. Anger gave him new strength; he raised the girl in his arms and turned towards the door communicating with the chapel. Framed in the opening was the hooded figure of Dr. Kassimere, confronting him. His face was immobile again, with the immobility of ibis-headed Thoth; his eyes were hard, his voice was cold. "What is the meaning of this outrage?" he demanded sternly. "Phryné has been taken suddenly ill; an immediate operation may be necessary----" "Out of my way!" said Dillon, advancing past a huge glass jar filled with reddish liquid that stood upon a pedestal between the couch and the door. "Be careful, you fool!" shrieked Dr. Kassimere, frenziedly, his calm dropping from him like a cloak and a new and dreadful light coming into the staring eyes.
