“Base calumny! I could drink as much more and bob up serenely at ten to-morrow. But I’m happy. Better let me be happy now. I was feeling sore enough the last time after I visited Dick’s. Hope my luck’ll change to-night.”

All at once it dawned on Frank of whom they were speaking of. He had thought the name of Dick Canfield familiar, and now he remembered hearing something of the history of the man who was known as proprietor of the biggest gambling-house in New York.

So they were on their way to a gambling-den! Now Frank knew he had made no mistake in thinking Jack Diamond in danger, and he was glad he had decided to accompany the party.

Merry had sized Herrick up as a sharp, but he was not sure about Madison. Either the latter was a clerk of some sort, or he was playing a part, and playing it well. But, without doubt, the Virginian was the chief game of the wolf that evening, for he had revealed that he possessed plenty of money.

Madison chattered on as they rolled northward along New York’s most fashionable thoroughfare. Diamond smoked steadily, but nervously, while Herrick was calm and sedate.

They turned into a side street and then halted almost immediately. Apparently they had stopped in front of a respectable private house in a most respectable portion of the city.

“Here we are,” said Herrick, and he was the first to leap out to the sidewalk, holding the door open for the others. Madison followed, then came Frank, and Jack got out last. Herrick was preparing to pay the driver.

“Excuse me, Charley,” put in the Virginian. “I think I informed you a while ago that I am paying to-night. I’ll settle this, and the man who bothers has to fight me at sunrise.”

Then he settled and they followed Herrick up the steps. The building might have been taken for the home of a retired banker, or the abode of a family physician in good standing.

They passed the first door, but a second, of oak and heavy enough to withstand a battering-ram, confronted them. Herrick pushed a button and they waited.
