In July 1543 he returned to Scotland; at least he returned with some "commissioners to England," who certainly came home in July 1543, as Knox mentions, though later he gives the date of Wishart's return in 1544, probably by a slip of the pen.
Coming home in July 1543, Wishart would expect a fair chance of preaching his novel ideas, as peace between Scotland and Protestant England now seemed secure, and Arran, the Scottish Regent, the chief of the almost Royal House of Hamilton, was, for the moment, himself a Protestant.

For five days (August 28-September 3, 1543) the great Cardinal Beaton, the head of the party of the Church, was outlawed, and Wishart's preaching at Dundee, about that date, is supposed by some {15b} to have stimulated an attack then made on the monasteries in the town.

But Arran suddenly recanted, deserted the Protestants and the faction attached to England, and joined forces with Cardinal Beaton, who, in November 1543, visited Dundee, and imprisoned the ringleaders in the riots.

They are called "the honestest men in the town," by the treble traitor and rascal, Crichton, laird of Brunston in Lothian, at this time a secret agent of Sadleir, the envoy of Henry VIII.

(November 25, 1543).
By April 1544, Henry was preparing to invade Scotland, and the "earnest professors" of Protestant doctrines in Scotland sent to him "a Scottish man called Wysshert," with a proposal for the kidnapping or murder of Cardinal Beaton.
