This gentleman was the Chevalier de Canaples.

He was strangely enough in a mood to be pleased by an anti-cardinalist ditty, for his rage against Andrea de Mancini--which he took no pains to conceal--had extended already to the Cardinal, and from morn till night he did little else but revile the whole Italian brood--as he chose to dub the Cardinal's family." I recognised the old knight's weak, vacillating character in this, a creature of moods that, like the vane on a steeple, turns this way or that, as the wind blows.
"I crave your patience, M.de Luynes," he continued, "and beg of you to hear my story so that you may determine whether you will save the Canaples from the danger that threatens them.

I only ask that you dispatch a reliable messenger to Blois.

But hear me out first.

In virtue as much of La Rochefoucauld's letters as of the sentiments which the Chevalier heard me express, I became the honoured guest at his chateau.
Three days after my arrival I sustained a shock by the unexpected appearance at Canaples of St.Auban.The Chevalier, however, refused him admittance, and, baffled, the Marquis was forced to withdraw.
