The indiscretion of De Luynes had been so great that a rumour of the perilous position of Concini did not fail to reach the ears of Richelieu. We have already stated that on his arrival at Court the Bishop of Luçon had been warmly patronized by the Italian favourite, who openly declared that he had found a man capable of giving a lesson _à tutti barboni_,[279] thereby alluding to the ancient ministers of Henri IV;[280] and that it was moreover through his agency that Marie de Medicis had appointed the wily prelate Secretary of State; but Richelieu was too subtle a diplomatist to allow a feeling of gratitude to interfere with his advancement; and he consequently no sooner ascertained beyond all possibility of mistake that his two patrons, the Queen-mother and her favourite, were about to succumb to the insidious attack of De Luynes, than, anxious to retain office, he hastened to despatch his brother-in-law, M. de Pontcourlay, to the latter, with instructions to offer his services, and to assure him that he had only consented to accept the charge which he then held in order that he might through this medium be enabled to devote himself to the interests of the King. Anxious to strengthen his party, De Luynes received the advances of Richelieu with great courtesy, although he was far from desiring the co-operation of so dangerous an ally; and a day or two subsequently the treacherous prelate was introduced into the private closet of Louis; where, in addition to his previous professions, he went so far as to pledge himself to the young monarch that he would give him timely intimation of the most hidden designs of the Queen-mother and the Maréchal d'Ancre. It was at length decided that Concini should die on Sunday the 23rd of April; but as the day approached Louis became terrified at his own audacity, and it required all the influence of De Luynes and his brothers to prevent his retracting the fatal order which he had given. He was too young coldly to contemplate treachery and murder, and withal so helpless in the event of failure, that his conscience and his timidity alike urged him to revoke the sentence of the unsuspecting victim; nor was he ultimately induced to persevere, until reminded by his insidious advisers that too many persons were now aware of his intentions for them to remain secret, should their execution be long delayed.
