I thought it was very strange that he should take a package, marked "private," with my name upon it. But nothing that he did could now be regarded as strange.

"When did he take it?" I inquired.

"Early this morning; as soon as you had gone to Mr. Collingsby's."

"The first time?"

"Yes; before nine o'clock."

"If Mr. Whippleton comes in again, Robert, don't lose sight of him for an instant. Follow him wherever he goes, if it is to the other side of the continent."

"Why—"

"Do as I tell you. I suppose Mr. Collingsby has the officers on his track by this time."

"You don't mean so!"
