The mystery of Beraud's murder was never solved. His estate of 200,000 livres was divided among three cousins, of whom the mother of Mme. Derues was one. Mme. Derues herself was entitled to a third of his mother's share of the estate, that is, one-ninth of the whole. But in 1775 Derues acquired the rest of the mother's share on condition that he paid her an annual income of 1,200 livres. Thus on the liquidation of the Duplessis inheritance Mme. Derues would be entitled nominally to some 66,500 livres, about L11,000 in English money. But five years had passed since the death of Despeignes-Duplessis, and the estate was still in the slow process of legal settlement. If Derues were to receive the full third of the Duplessis inheritance--a very unlikely supposition after four years of liquidation--66,000 livres would not suffice to pay his ordinary debts quite apart from the purchase money of Buisson-Souef. His financial condition was in the last degree critical. Not content with the modest calling of a grocer, Derues had turned money-lender, a money-lender to spendthrift and embarrassed noblemen. Derues dearly loved a lord; he wanted to become one himself; it delighted him to receive dukes and marquises at the Rue Beaubourg, even if they came there with the avowed object of raising the wind. The smiling grocer, in his everlasting bonnet and flowered dressing-gown a la J. J. Rousseau, was ever ready to oblige the needy scion of a noble house. What he borrowed at moderate interest from his creditors he lent at enhanced interest to the quality. Duns and bailiffs jostled the dukes and marquises whose presence at the Rue Beaubourg so impressed the wondering neighbours of the facile grocer. This aristocratic money-lending proved a hopeless trade; it only plunged Derues deeper and deeper into the mire of financial disaster. The noblemen either forgot to pay while they were alive, or on their death were found to be insolvent. Derues was driven to ordering goods and merchandise on credit, and selling them at a lower price for ready money. Victims of this treatment began to press him seriously for their money or their goods. Desperately he continued to fence them off with the long expected windfall of the Duplessis inheritance.
