Treherne was trembling in every fiber. Cold drops of moisture had started on his brow. His eyes were dilated and quickly glancing, as he contemplated this obsession to which neither dared to refer openly, lest the slight bonds that held the mania within bounds, the exhaustion of the spasm of insanity, called the lucid interval, be overstrained and snap at once.

“I believe I would not meet it here, in the world,—away from where it has been so long,” he said doggedly.

“What would you do if you should? You might hurt yourself,—and Hugh, and this you would deplore more, you might injure some one else,” said the doctor.

Treherne suddenly turned, throwing his arms about Colonel Kenwynton in a paroxysm of energy.

“Colonel, lead the way. Go with me, for I would follow you to hell if you led the charge. God knows I have done that often enough. Lead the charge, Colonel!”

“Yes, come with us, Colonel,” said the alienist cordially,—it could but seem a sinister sort of hospitality. “We should be delighted to entertain you for a few days, or, indeed, as long as you will stay. It is not a public institution, but we have a beautiful place,—haven’t we, Hugh?—something very extra in the way of conservatories. Hugh has begun to take much interest in our orchids. It is a good distance, but Mr. Ducie drove me down here from Caxton with his fast horse in less time than I could have imagined.”

“Mr. Ducie?” said Adrian Ducie, with a start. “Where is he? Has he gone?”

The doctor stared as if he himself had taken leave of his senses. “You remember,” he said confusedly, blending the reminder with an air of explanation to the group generally, “that when we had that game of billiards at your hotel in Caxton last evening I asked you a question or two about the Duciehurst estate; I didn’t like to say much, but your replies gave me the clew as to where Captain Treherne had gone after his escape from the Glenrose sanatorium. He had inquired about Duciehurst as soon as he began to recover his memory, and seemed to recur to the subject and to brood upon it. The idea stayed with me all night, for I was very anxious, and about daybreak I took the liberty of rousing you by telephone to ask if the roads here from Caxton were practicable for a motor-car. You remember, don’t you?”

He paused, looking in some surprise at Adrian.

“You told me,” he continued, “that the roads would be impracticable after these rains, and as I disclosed the emergency, in my great perturbation for Captain Treherne’s safety, you offered to drive me down, as you had an exceptionally speedy horse which you kept for your easy access from Caxton to the several plantations that you lease in this vicinity.”
