Thénardier, the reader will remember, although he had been Marius’ neighbor, had never seen him, which is not unusual in Paris; he had formerly, in a vague way, heard his daughters talk of a very poor young man named Marius who lived in the house. He had written to him, without knowing him, the letter with which the reader is acquainted.
No connection between that Marius and M. le Baron Pontmercy was possible in his mind.
As for the name Pontmercy, it will be recalled that, on the battlefield of Waterloo, he had only heard the last two syllables, for which he always entertained the legitimate scorn which one owes to what is merely an expression of thanks.
