As soon as Brian received the telegram which announced the death of Mark Frettlby, he put on his hat, stepped into Calton’s trap, and drove along to the St. Kilda station in Flinders Street with that gentleman. There Calton dismissed his trap, sending a note to his clerk with the groom, and went down to St. Kilda with Fitzgerald. On arrival they found the whole house perfectly quiet and orderly, owing to the excellent management of Sal Rawlins. She had taken the command in everything, and although the servants, knowing her antecedents, were disposed to resent her doing so, yet such were her administrative powers and strong will, that they obeyed her implicitly. Mark Frettlby’s body had been taken up to his bedroom, Madge had been put to bed, and Dr. Chinston and Brian sent for. When they arrived they could not help expressing their admiration at the capital way in which Sal Rawlins had managed things.

“She’s a clever girl that,” whispered Calton to Fitzgerald. “Curious thing she should have taken up her proper position in her father’s house. Fate is a deal cleverer than we mortals think her.”

Brian was about to reply when Dr. Chinston entered the room. His face was very grave, and Fitzgerald looked at him in alarm.

“Madge — Miss Frettlby,” he faltered.

“Is very ill,” replied the doctor; “has an attack of brain fever. I can’t answer for the consequences yet.”

Brian sat down on the sofa, and stared at the doctor in a dazed sort of way. Madge dangerously ill — perhaps dying. What if she were to die, and he to lose the true-hearted woman who stood so nobly by him in his trouble?

“Cheer up,” said Chinston, patting him on the shoulder; “while there’s life there’s hope, and whatever human aid can do to save her will be done.”

Brian grasped the doctor’s hand in silence, his heart being too full to speak.

“How did Frettlby die?” asked Calton.

“Heart disease,” said Chinston. “His heart was very much affected, as I discovered a week or so ago. It appears he was walking in his sleep, and entering the drawing-room, he alarmed Miss Frettlby, who screamed, and must have touched him. He awoke suddenly, and the natural consequences followed — he dropped down dead.”

“What alarmed Miss Frettlby?” asked Brian, in a low voice, covering his face with his hand.

“The sight of her father walking in his sleep, I suppose,” said Chinston, buttoning his glove; “and the shock of his death which took place indirectly through her, accounts for the brain fever.”

“Madge Frettlby is not the woman to scream and waken a somnambulist,” said Calton, decidedly, “knowing as she did the danger. There must be some other reason.”

“This young woman will tell you all about it,” said Chinston, nodding towards Sal, who entered the room at this moment. “She was present, and since then has managed things admirably; and now I must go,” he said, shaking hands with Calton and Fitzgerald. “Keep up your heart, my boy; I’ll pull her through yet.”

After the doctor had gone, Calton turned sharply to Sal Rawlins, who stood waiting to be addressed.

“Well,” he said briskly, “can you tell us what startled Miss Frettlby?”

“I can, sir,” she answered quietly. “I was in the drawing-room when Mr. Frettlby died — but — we had better go up to the study.”

“Why?” asked Calton, in surprise, as he and Fitzgerald followed her up stairs.

“Because, sir,” she said, when they had entered the study and she had locked the door, “I don’t want any one but yourselves to know what I tell you.”

“More mystery,” muttered Calton, as he glanced at Brian, and took his seat at the escritoire.

“Mr. Frettlby went to bed early last night,” said Sal, calmly, “and Miss Madge and I were talking together in the drawing-room, when he entered, walking in his sleep, and carrying some papers — ”

Both Calton and Fitzgerald started, and the latter grew pale.

“He came down the room, and spread out a paper on the table where the lamp was. Miss Madge bent forward to see what it was. I tried to stop her, but it was too late. She gave a scream, and fell on the floor. In doing so she happened to touch her father. He awoke, and fell down dead.”

“And the papers?” asked Calton, uneasily.

Sal did not answer, but producing them from her pocket, laid them in his hands.

Brian bent forward, as Calton opened the envelope in silence, but both gave vent to an exclamation of horror at seeing the certificate of marriage which they knew Rosanna Moore had given to Whyte. Their worst suspicions were confirmed, and Brian turned away his head, afraid to meet the barrister’s eye. The latter folded up the papers thoughtfully, and put them in his pocket.

“You know what these are?” he asked Sal, eyeing her keenly.

“I could hardly help knowing,” she answered; “it proves that Rosanna Moore was Mr. Frettlby’s wife, and — ” she hesitated.

“Go on,” said Brian, in a harsh tone, looking up.

“And they were the papers she gave Mr. Whyte.”

“Well!”

Sal was silent for a moment, and then looked up with a flush.

“You needn’t think I’m going to split,” she said, indignantly, recurring to her Bourke Street slang in the excitement of the moment. “I know what you know, but I’ll be as silent as the grave.”

“Thank you,” said Brian, fervently, taking her hand; “I know you love her too well to betray this terrible secret.”

“I would be a nice ’un, I would,” said Sal, with a scorn, “after her lifting me out of the gutter, to round on her — a poor girl like me, without a friend or a relative, now Gran’s dead.”

Calton looked up quickly. It was plain Sal was quite ignorant that Rosanna Moore was her mother. So much the better; they would keep her in ignorance, perhaps not altogether, but it would be folly to undeceive her at present.

“I’m goin’ to Miss Madge now,” she said, going to the door, “and I won’t see you again; she’s getting light-headed, and might let it out; but I’ll not let any one in but myself,” and so saying, she left the room.
