No argument would bend his obstinate conviction, and he debated with great force from his own standpoint. He presented a man overmastered and mentally incapable of appreciating any argument against his possession.

But Sir Walter, now determined, was as obstinate as the clergyman. Mannering bluntly declared that it would be suicide on May's part, and a conniving at the same by any who permitted him to attempt his vigil.

"I, too, must do my duty as I see it," summed up the master of Chadlands, "and after I have done so, then we may be in a position to admit the case is altered."

The other suddenly rose and lifted his hands. He was trembling with emotion.

"May my God give a sign, then!" he cried.

They were silent a moment, for courtesy or astonishment. Nothing happened, and presently Sir Walter spoke:

"You must bear with me. You are upset, and scarcely know the gravity of the things you say. To-morrow the physical and material investigation that I consider proper, and the world has a right to demand, will be made—in a spirit, I hope, as earnest and devout as your own. And if after that no shadow of explanation is forthcoming, and no peril to life can be discovered, then I should feel disposed to consider your views more seriously—with many reserves, however. At any rate, it will be your turn then, if you still adhere to your opinions; and I am sure all just persons who hear of your purpose would join their prayers with you."

"Your faith is weak, though you believe it strong," answered the other.

And he was equally curt when the physician advised him to take a sleeping-draught before retiring. He bade them "Good-night" without more words, and went to his room, while after further conversation, Dr. Mannering and Mr. Prodgers took their leave.

The former strongly urged Sir Walter to set some sort of guard outside the door of the Grey Room.
