Others were playing dice or talking and smoking their cheroots, and the hum of conversation came upon the air.
“By Jove!” exclaimed Frank, with a thrill, “I tell you, Barney, we have found the den of Costello and his gang.”
“Begorra, that’s thrue,” agreed Barney.
“It is certainly a place well suited for the purpose.”
“I should say so, sor. But however will we get out of here?”
“That is a question.”
“Shure, sor, I think we’d betther get out as soon as possible.”
