The three talked the matter over for some time, but could reach no satisfactory conclusion regarding Frederic Vernon's departure from the hotel.

"I think it will be best to take the bull by the horns, and have Mrs. Vernon released without delay," said the detective. "Unless we do that her nephew may get it into his head to have her taken a long distance off."

This was thought good advice, and leaving the hotel they told the hackman to drive them to Dr. Rushwood's Sanitarium.

"Sure an' I'm havin' a long spell av it," grinned the Jehu.

"So you are," answered Robert. "But you shall be fully paid for your work."

"Is somethin' wrong?"

"Very much wrong, and we are going to set it right."

"Thin Mike Grady is wid yez to the end," said the hack driver, as he slammed shut the door of his turnout.

When they reached the asylum they saw that all of the lower rooms were dark. In two of the upper apartments lights were burning.

"Come around and I will show you the room in which Mrs. Vernon is confined," said our hero.
