Murray was proclaimed regent on the 22d of August. Soon afterward began the machinations for accusing Mary of Darnley's murder; and Murray's first care was to put out of the way every witness whose testimony could be of any importance. Hay, Hepburn, and Powrie and Dalgleish, on whom the queen's letters were said to have been found, were all tried, convicted, and executed on the same day. It was remarked that the proceedings were conducted with extraordinary and indecent haste. Hay and Hepburn, from the scaffold, denounced the nobles who had "made a bond for the king's murder." Public confidence was shaken in the regent, and the discontent of the people was expressed in plain speech and satirical ballads. Murray began to feel the need of Elizabeth's assistance. Mary, in her trusting confidence, had voluntarily placed all her valuable jewels in Murray's hands, for safe keeping. From among them he selected a set of rare pearls, the most valuable in Europe, which he sent by an agent to Elizabeth, who agreed to purchase what she well knew he had no right to sell. Under such circumstances, as is the custom among thieves and receivers, she expected a bargain, and got it. It was a very pretty transaction. In May, 1568, Mary escaped from Lochleven castle, and in a few days found herself at the head of an army of six thousand men. Of the ten earls and lords who flew to her support, nine were Protestants; and our Puritan historian finds it remarkable that, in spite of all the efforts of Murray and his faction, and in spite of all the violence of the preachers, she--the Catholic Queen of Scotland, the daughter of the hated house of Guise, the reputed mortal enemy of their religion--should now, after being maligned as the most abandoned of her sex, find her best friends among her own Protestant subjects, appears at first sight inexplicable. A phenomenon so strange, he adds, admits of only one explanation. If, throughout her reign, she had not loyally kept her promises of security and toleration to her Protestant subjects, they assuredly would not, in her hour of need, have risked their lives and fortunes in her defence.
