Enraged at these disappointments, he attempted to make his peace with the court of France, and offered his services, in a letter to one Moreau, a banker in Paris.

This packet, which he endeavoured to transmit by the way of Portugal, was intercepted, and a warrant issued out to apprehend him for high-treason.
When the messenger disarmed him in St.James's Park, he exhibited marks of guilty confusion and despair, and begged that he would kill him directly.

Being conveyed to the cockpit, in a sort of frenzy, he perceived a penknife lying upon a table, and took it up without being perceived by the attendants.

A committee of council was immediately summoned, and Guiscard brought before them to be examined.

Finding that his correspondence with Moreau was discovered, he desired to speak in private with secretary St.John, whom in all probability he had resolved to assassinate.
