On February 20th, 1806, he disclosed to Talleyrand the details of a supposed plot for the murder of the French Emperor, which some person had proposed to him, an offer which he rejected with horror, at the same time ordering the man to be expelled from the kingdom.

It is more than probable that the whole thing was got up by the French police as a test of the esteem which Fox had always expressed for Bonaparte.
The experiment having turned out well, Talleyrand assured Fox of the pacific desires of the French Emperor as recently stated to the Corps Legislatif, namely, that peace could be had on the terms of the Treaty of Amiens.

Fox at once clasped the outstretched hand, but stated that the negotiations must be in concert with Russia, and the treaty such as our allies could honourably accept.

To this Talleyrand, on April 1st, gave a partial assent, adding that Napoleon was convinced that the rupture of the Peace of Amiens was due solely to the refusal of France to grant a treaty of commerce.

France and England could now come to satisfactory terms, if England would be content with the sovereignty of the seas, and not interfere with Continental affairs.[78] France desired, not a truce, but a durable peace.
To this Fox assented, but traversed the French claim that Russia's participation would imply her mediation.
