As Mimi drew near the Castle, she saw no lights except those in and around the tower room.  The lights showed her that Mr. Caswall was there, so she entered by the hall door, which as usual was open, and felt her way in the darkness up the staircase to the lobby of the room.  The door was ajar, and the light from within showed brilliantly through the opening.  She saw Edgar Caswall walking restlessly to and fro in the room, with his hands clasped behind his back.  She opened the door without knocking, and walked right into the room.  As she entered, he ceased walking, and stared at her in surprise.  She made no remark, no comment, but continued the fixed look which he had seen on her entrance.

For a time silence reigned, and the two stood looking fixedly at each other.  Mimi was the first to speak.

“You murderer!  Lilla is dead!”

“Dead!  Good God!  When did she die?”

“She died this afternoon, just after you left her.”

“Are you sure?”

“Yes—­and so are you—­or you ought to be.  You killed her!”

“I killed her!  Be careful what you say!”

“As God sees us, it is true; and you know it.  You came to Mercy Farm on purpose to break her—­if you could.  And the accomplice of your guilt, Lady Arabella March, came for the same purpose.”

“Be careful, woman,” he said hotly.  “Do not use such names in that way, or you shall suffer for it.”

“I am suffering for it—­have suffered for it—­shall suffer for it.  Not for speaking the truth as I have done, but because you two, with devilish malignity, did my darling to death.  It is you and your accomplice who have to dread punishment, not I.”

“Take care!” he said again.

“Oh, I am not afraid of you or your accomplice,” she answered spiritedly.  “I am content to stand by every word I have said, every act I have done.  Moreover, I believe in God’s justice.  I fear not the grinding of His mills; if necessary I shall set the wheels in motion myself.  But you don’t care for God, or believe in Him.  Your god is your great kite, which cows the birds of a whole district.  But be sure that His hand, when it rises, always falls at the appointed time.  It may be that your name is being called even at this very moment at the Great Assize.  Repent while there is still time.  Happy you, if you may be allowed to enter those mighty halls in the company of the pure-souled angel whose voice has only to whisper one word of justice, and you disappear for ever into everlasting torment.”

The sudden death of Lilla caused consternation among Mimi’s friends and well-wishers.  Such a tragedy was totally unexpected, as Adam and Sir Nathaniel had been expecting the White Worm’s vengeance to fall upon themselves.

Adam, leaving his wife free to follow her own desires with regard to Lilla and her grandfather, busied himself with filling the well-hole with the fine sand prepared for the purpose, taking care to have lowered at stated intervals quantities of the store of dynamite, so as to be ready for the final explosion.  He had under his immediate supervision a corps of workmen, and was assisted by Sir Nathaniel, who had come over for the purpose, and all were now staying at Lesser Hill.
