"Why, in that case, my wife and your wife must at least keep up a correspondence," exclaimed Valentine's husband, more hopefully.

"True, but I discover this fact to-day for the first time, monsieur."

"Monsieur, I implore you, I adjure you, to open this letter. It is addressed to my wife. I will assume the whole responsibility."

"Here is the letter; read it, monsieur," responded M. de Luceval, quite as eager to know the contents of the missive as M. d'Infreville.

The latter gentleman, after hastily perusing the note, exclaimed:

"Read it, monsieur. It is surely enough to drive one mad, for in this letter your wife reminds my wife of the delightful day they spent together yesterday, as well as last Wednesday, and begs her to come again on Sunday."

"And I assure you, upon my word of honour, monsieur," responded M. de Luceval, after having perused the note in his turn, "that yesterday my wife did not get up until noon, that about three o'clock, I, with no little difficulty, succeeded in persuading her to take a drive with me. We returned a short time before dinner, and after dinner two friends of ours spent the evening with us. As regards Wednesday, I remember perfectly that I was in and out of my wife's room a number of times, and I again assure you, upon my word of honour, that Madame d'Infreville did not spend the day at our house."

"Then, how do you explain this letter, monsieur?"
