"Look out," whispered Sam. "I'll bet this is another pay-as-you-enter game; then they won't give you anything to eat after you get in."
"I do not understand you, sir. Why should we go with you?"
"The carriage awaits you at the door."

"Mr. Daniel Davis and Mr. Samuel Hickey are requested to dine with the Spanish ambassador, Señor Guillermo Martinez, this evening at 8.30 o'clock."
Dan opened his eyes wide when he read this, then passed the invitation to his chum. Sam perused it, cocked one eye up and winked at Dan.
"We seem to be getting quite popular. What are you going to do?"
