"Yes. Do we?"

"Yes. Your young friend Calladine, by the way, will join us in your box."

"That is very kind of him, I am sure," said Mr. Ricardo.

The two men arrived before the rising of the curtain, and in the crowded lobby a stranger spoke a few words to Hanaud, but what he said Ricardo could not hear. They took their seats in the box, and Hanaud looked at his programme.

"Ah! It is Il Ballo de Maschera to-night. We always seem to hit upon something appropriate, don't we?"

Then he raised his eyebrows.

"Oh-o! Do you see that our pretty young friend, Joan Carew, is singing in the rôle of the page? It is a showy part. There is a particular melody with a long-sustained trill in it, as far as I remember."

Mr. Ricardo was not deceived by Hanaud's apparent ignorance of the opera to be given that night and of the part Joan Carew was to take. He was, therefore, not surprised when Hanaud added:

"By the way, I should let Calladine find it all out for himself."

Mr. Ricardo nodded sagely.
