"Harper, are you aware that the murdered messenger was my friend?"

"Was he?"

"Certainly. I would be less than human did I refuse to take the trail of his vile assassins. You make me blush when you insinuate that danger should deter me from doing my duty."

"I am not aware that I said such a thing," answered Elliston. "I did not mean it if I did. It would please me to have you remain off this trail, however, Dyke. I will see to it that the best Chicago detectives are set to work; that ought to satisfy you."

"And I sit with my hands folded meantime?"

A look of questioning surprise filled the eyes of Dyke Darrel, as he regarded Mr. Elliston.

"No. But you promised Nell to take her East this spring, to New York-"

"He did, but I forego that pleasure," cried the girl, quickly. "I realize that Dyke has a duty to perform in Illinois."

"And so you, too, side with your brother," cried Mr. Elliston, forcing a laugh. "In that case, I surrender at discretion."

Dyke picked up and examined the paper once more. "DIED FOR DUTY. BOLD AND BLOODY CRIME AT NIGHT ON THE CENTRAL RAILROAD."
