"Permit me to interrupt you an instant, my dear abbé," said Célestin, hastily.

"What is it, my dear boy?"

"M. and Madame de la Rochaiguë are not very regular in the performance of their religious duties, but Mlle. Helena never misses a service."

"That is true."

"It will be only natural, then, that she should take Mlle. de Beaumesnil to the Church of St. Thomas d'Aquin, that being the church she always attends."

"Evidently."

"It would be well, then, for her to perform her devotions at the altar of the Virgin, where she will also conduct her young friend to-morrow morning at nine o'clock. I would also suggest that the ladies take their places to the left of the altar."

"To the left of the altar! and why, Célestin?"

"Because I shall be performing my devotions at the same altar."

"Excellent!" cried the abbé, "no better plan could be devised. Mlle. Helena shall call the girl's attention to you, and you will make an admirable impression from the very first. A very clever idea, my dear Célestin, a very clever idea!"
