But soon a new danger appeared from an unexpected quarter. Darnley was a vain and foolish youth who treated his wife with but scanty respect. He wished to be sovereign of Scotland, to secure the crown for the family of Lennox to the exclusion of the Hamiltons, and to force the queen to follow his counsels in all matters of state. As his wishes were not granted he determined to revenge himself on Mary's secretary, David Riccio, whom he pretended to regard as Mary's secret adviser. For this purpose he turned for assistance to the reformed party whose fears had been aroused by Mary's religious policy. A confederation was formed consisting of Darnley, the Earl of Morton, Lord Ruthven, and Lindsay for the murder of Riccio. The Earl of Lennox Darnley's father, Moray, Argyll, and Maitland of Lethington, the English ambassador, and apparently John Knox, were aware of the design and approved of it.[26] When everything was ready for the opening of Parliament the murderers forced their way into the presence of the queen, and slew her secretary almost in her presence (9 March 1566). On the next day Darnley issued a proclamation ordering those who had assembled for the Parliament to leave Edinburgh, and on the same evening the Earl of Moray arrived in the capital. The conspirators had agreed to proclaim Darnley king of Scotland. For this purpose the queen was to be held a prisoner or to be slain if she attempted to make her escape, but she succeeded in eluding the vigilance of her captors and in making her way to Dunbar, where she was joined by Archbishop Hamilton, the Earls of Huntly, Atholl, and Bothwell. She advanced on Edinburgh without meeting any resistance, while the murderers of Riccio were obliged to make their escape into England. Darnley deserted his fellow conspirators by communicating to the queen the details of the plot. His desertion did not, however, gain him the dictatorship he desired, as Mary pardoned Moray and Argyll, and received them together with Huntly, Atholl, and Bothwell into her councils. The birth of an heir to the throne would, it was thought, lead to a better understanding between Mary and her husband, but unfortunately it had no result. Though the baptism of the prince was carried out in the chapel-royal of Stirling Castle with all the pomp and splendour of Catholic ceremonial (December 1566) Darnley refused to be present or to take any part in the festivities. A few days later Morton and the other murderers of Riccio were pardoned, and allowed to return to Scotland.
