"We'll sing you an anthem some day," Angelica presently promised.

"Why not now?" said Evadne.

"The spirit does not move us," Diavolo answered.

"But you may forget," said Evadne.

"We never forget our promises," Angelica protested as proudly as was
possible with a green nose.

Nor did they, curiously enough. They made a point of keeping their word,
but in their own way, and this one was kept in due course. The time they
chose was when a certain Grand Duke was staying in the house. They had
quite captivated him, and he expressed a wish to hear them sing.

"Shall we?" said Diavolo,

"We will," said Angelica, "Not because he's a prince, but because we
promised Evadne an anthem, and we might as well do it now," she added with
true British independence.

The prince chuckled.

"What shall it be?" said Diavolo, settling himself at the piano. He always
played the accompaniments.

"_Papa_, I think," said Angelica.
