ing down, as swiftly recoiled. "What
does this mean?" he hoarsely cried.

Ravenshaw did not speak.

"Miss Sisily fell over the cliffs by the Moon Rock," said Thalassa. "I
went down for her, but it was too late. She was drowned."

Austin's look sought Ravenshaw's, who nodded in confirmation.

"More horror--more misery," whispered Austin. A shudder ran through him.
"I do not understand," he said simply. "Thalassa?"

"It's not for me to explain," said Thalassa quickly.

"You then, Ravenshaw."

Ravenshaw spoke slowly.

"They have been looking for the man who killed Robert Turold--your
brother. Well, I am he."

"You!" gasped Austin, in a choking voice. "What do you mean? I do not
understand you. My son has been arrested."

"He has been arrested wrongly, then. It is I--I alone am responsible."

Austin groped for his glasses like a man suddenly enveloped in darkness.
His fingers closed on them and adjusted them on the bridge of his nose.
Through them he surveyed the man before him with close attention.

"Ravenshaw," he said gravely, "either you are mad or I am. Did not my
sister call here to see you on the night my brother was killed, and did
you not go with her to Flint House and break into my brother's room? How,
then, could you have killed Robert? Besides, I saw my son at Penzance
to-day. He tells me he is innocent, and that the murderer is a man whom
Robert and Thalassa robbed and wounded on a lonely island thirty years
ago, and left there for dead, as they thought. What does it all mean?"

"These things can all be explained," replied Ravenshaw. "It is a long
story. Sit down, and I will tell it to you."

"Not here--not here!" replied Austin unsteadily. His glance went to the
corner of the room and the tranquil figure on the couch. He hid his face
for a moment in his hands, then said: "Let us go to another room."

Ravenshaw made a sad gesture of acquiescence. "Come," he said quietly,
lifting the lamp from the table. The other two followed him, and Thalassa
closed the surgery door gently behind them. The doctor led them into a
sitting-room opposite, where they seated themselves. After a moment's
silence Ravenshaw began to speak in low controlled tones which gave no
indication of the state of his feelings.

"You know all about this island part of the story," he said, inquiringly,
"how your brother and Remington, seeking their fortune together, came to
be there?"

Austin Turold nodded.

"I am Remington,"
