Nino smiled.

Valeria held the postcard out for him to see, and covering everything but the last line, said: "What does 'cr' mean?"

Nino looked, and said: "Where does he write from?"

Nancy and Valeria exchanged glances, and decided that they could trust Nino. He would not use the system or give it to other people. Besides, the system had a flaw.

"Monte Carlo," they said in unison.

Nino made a mouth as if to whistle, and did not whistle. The baby sitting on the rug watched him and wished he would do it again.

"I suppose 'cr' is croupier," said Nino. Then there was silence. After a while Nino said: "How much did he take with him?"

"Everything," said Valeria.

Then Nino made the mouth again, and the baby was pleased.

"You had better go and fetch him. Quick!" said Nino, looking at Nancy.
