"The Doctor looked in once without saying anything," replied Robertson, who sat up as soon as Wallion came in, more wide awake and expectant than he had seen him yet. "What has been going on? I heard steps and voices.... Where is my daughter?"

"You must take things quietly now," said Wallion kindly. "I can't explain matters just at present, but there is nothing to be alarmed about. Your daughter has left the house, but you will have news of her soon. You have done with your tormentors now, for good and all, and I shall put you under the care of a really trustworthy person."

At this point McTuft and his assistant, a young, pleasant-looking official named Johnstone, entered the room.

"There are two things you must do, Johnstone," was Wallion's greeting as he hurriedly scribbled a few lines on a card. "First of all you must take Mr. Robertson to the Pacific Hotel, give this card to the manager and see that he is properly looked after. Secondly, alarm the police. They must track the individuals whose names I have written down: Edward A. Dixon, Doctor Augustus N. Corman, Madame Lorraine and Ricardo Ferail, commonly called 'Toroni'; the last is guilty of murder, the others are accomplices."

Johnstone wrote down the names.

"They have only just driven away in Dixon's car, and under false pretenses induced Miss Elaine Robertson to accompany them," said Wallion more deliberately. "Her father, Mr. Robertson, need not be told, but he may give information respecting their motives and actions; got that down?"

"Yes," answered the young official with enthusiasm and, grinning at McTuft, observed: "'Hotel Dixon' is in for it this time. Just think of it!"

"That's good," said Wallion, "but you must provide yourselves with another car, the one that is here we shall want for ourselves; au revoir, Mr. Robertson, and don't you worry," he concluded, shaking hands heartily with the bewildered man, after which he hurried away.

It was past eleven, and darker than ever, when Wallion, Murner and McTuft ran down the drive to the gates. By the light of McTuft's pocket-lamp they could distinctly see the traces of Dixon's car on the damp road.

"They have taken a northerly direction, probably for the coast..." said McTuft.
