"Oh!" he laughed shortly.

"I was just joking, Gustavo." Gustavo bowed and turned down the corridor; there was a look on Tony's face that did not encourage confidences.

"I am going away tomorrow morning--by the first boat this time--and you mustn't let my aunt and sister know.

I will write two letters and you are to take them down to the steward of the boat that leaves tonight.

Ask him to put on Austrian stamps and mail them at Riva, so they'll get back here tomorrow.
