His sullen behaviour in all probability first infused this opinion, which was strengthened and confirmed by the insinuations of his enemies.

The Scots who had come up to London to give an account of the proceedings in their parliament, were infected with the same notion.

One Simpson, a presbyterian of that country, whom the earl of Portland employed as a spy, had insinuated himself into the confidence of Nevil Payne, an active and intelligent partisan and agent of king James; by which means he supplied the earl with such intelligence as raised him to some degree of credit with that minister.

This he used in prepossessing the earl against the king's best friends, and infusing jealousies which were soon kindled into mutual distrust and animosity.
PLOT AGAINST THE GOVERNMENT.
Sir James Montgomery, who had been a warm advocate for the revolution, received advice that the court suspected him and others of disaffection, and was employed in seeking evidence by which they might be prosecuted.
They were equally alarmed and incensed at this intimation, and Payne seized the opportunity of seducing them into a correspondence with the exiled king.

They demanded the settlement of the presbytery in Scotland, and actually engaged in a treaty for his restoration.
