It was the gate bell, which rang simultaneously in house and clinic, that broke the tension at last. She heard the catlike tread of Surama on the walk as he left the clinic to answer it; and then, with an almost hysterical sigh of relief, she caught the firm, familiar accents of Dalton in conversation with the sinister attendant. Rising, she almost tottered to meet him as he loomed up in the library doorway; and for a moment no word was spoken while he kissed her hand in his courtly, old-school fashion. Then Georgina burst forth into a torrent of hurried explanation, telling all that had happened, all she had glimpsed and overheard, and all she feared and suspected.

Dalton listened gravely and comprehendingly, his first bewilderment gradually giving place to astonishment, sympathy, and resolution. The message, held by a careless clerk, had been slightly delayed, and had found him appropriately enough in the midst of a warm lounging-room discussion about Clarendon. A fellow-member, Dr. MacNeil, had brought in a medical journal with an article well calculated to disturb the devoted scientist, and Dalton had just asked to keep the paper for future reference when the message was handed him at last. Abandoning his half-formed plan to take Dr. MacNeil into his confidence regarding Alfred, he called at once for his hat and stick, and lost not a moment in getting a cab for the Clarendon home.

Surama, he thought, appeared alarmed at recognizing him; though he had chuckled as usual when striding off again toward the clinic. Dalton always recalled Surama's stride and chuckle on this ominous night, for he was never to see the unearthly creature again. As the chuckler entered the clinic vestibule his deep, guttural gurgles seemed to blend with some low mutterings of thunder which troubled the far horizon.

When Dalton had heard all Georgina had to say, and learned that Alfred was expected back at any moment with an hypodermic dose of morphine, he decided he had better talk with the doctor alone. Advising Georgina to retire to her room and await developments, he walked about the gloomy library, scanning the shelves and listening for Clarendon's nervous footstep on the clinic path outside. The vast room's corners were dismal despite the chandelier, and the closer Dalton looked at his friend's choice of books the less he liked them. It was not the balanced collection of a normal physician, biologist, or man of general culture. There were too many volumes on doubtful borderland themes; dark speculations and forbidden rituals of the Middle Ages, and strange exotic mysteries in alien alphabets both known and unknown.

The great notebook of observations on the table was unwholesome, too. The handwriting had a neurotic cast, and the spirit of the entries was far from reassuring. Long passages were inscribed in crabbed Greek characters, and as Dalton marshaled his linguistic memory for their translation he gave a sudden start, and wished his college struggles with Xenophon and Homer had been more conscientious. There was something wrong—something hideously wrong—here, and the governor sank limply into the chair by the table as he pored more and more closely over the doctor's barbarous Greek. Then a sound came, startlingly near, and he jumped nervously at a hand laid sharply on his shoulder.

"What, may I ask, is the cause of this intrusion? You might have stated your business to Surama."

Clarendon was standing icily by the chair, the little gold syringe in one hand. He seemed very calm and rational, and Dalton fancied for a moment that Georgina must have exaggerated his condition. How, too, could a rusty scholar be absolutely sure about these Greek entries? The governor decided to be very cautious in his interview, and thanked the lucky chance which had placed a specious pretext in his coat pocket. He was very cool and assured as he rose to reply.

"I didn't think you'd care to have things dragged before a subordinate, but I thought you ought to see this article at once."

He drew forth the magazine given him by Dr. MacNeil and handed it to Clarendon.

"On page 542—you see the heading, 'Black Fever Conquered by New Serum.' It's by Dr. Miller of Philadelphia—and he thinks he's got ahead of you with your cure. They were discussing it at the club, and MacNeil thought the exposition very convincing. I, as a layman, couldn't pretend to judge; but at all events I thought you oughtn't to miss a chance to digest the thing while it's fresh. If you're busy, of course, I won't disturb you——"
