On Wednesday evening, the day after his death, Dubois was carried from Versailles to the church of the chapter of Saint-Honore, in Paris, where he was interred some days after.  Each of the academies of which he was a member had a service performed for him (at which they were present), the assembly of the clergy had another (he being their president); and as prime minister he had one at Notre Dame, at which the Cardinal de Noailles officiated, and at which the superior courts were present.  There was no funeral oration at any of them.  It could not be hazarded.  His brother, more modest than he, and an honest man, kept the office of secretary of the cabinet, which he had, and which the Cardinal had given him.  This brother found an immense heritage.  He had but one son, canon of Saint-Honore, who had never desired places or livings, and who led a good life.  He would touch scarcely anything of this rich succession.  He employed a part of it in building for his uncle a sort of mausoleum (fine, but very modest, against the wall, at the end of the church, where the Cardinal is interred, with a Christian-like inscription), and distributed the rest to the poor, fearing lest this money should bring a curse upon him.

It was found some time after his death that the Cardinal had been long married, but very obscurely!  He paid his wife to keep silent when he received his benefices; but when he dawned into greatness became much embarrassed with her.  He was always in agony lest she should come forward and ruin him.  His marriage had been made in Limousin, and celebrated in a village church.  When he was named Archbishop of Cambrai he resolved to destroy the proofs of this marriage, and employed Breteuil, Intendant of Limoges, to whom he committed the secret, to do this for him skilfully and quietly.

Breteuil saw the heavens open before him if he could but succeed in this enterprise, so delicate and so important.  He had intelligence, and knew how to make use of it.  He goes to this village where the marriage had been celebrated, accompanied by only two or three valets, and arranges his journey so as to arrive at night, stops at the cure’s house, in default of an inn, familiarly claims hospitality like a man surprised by the night, dying of hunger and thirst, and unable to go a step further.

The good cure; transported with gladness to lodge M. l’Intendant, hastily prepared all there was in the house, and had the honour of supping with him, whilst his servant regaled the two valets in another room, Breteuil having sent them all away in order to be alone with his host.  Breteuil liked his glass and knew how to empty it.  He pretended to find the supper good and the wine better.
