Thus, whilst leaving him perfect freedom of movement within his own apartments, he would yet ensure against his escape so that should Robespierre demand him he could without difficulty be produced.
To this end he repaired with a sous-lieutenant and six men to La Boulaye's house in the Rue Nationale, intending to station the soldiers there with orders not to allow the Deputy to go out, and to detain and question all who sought admittance to him.

He nourished the hope that the ci-devant Vicomte might still be with La Boulaye.

At the Rue Nationale, however, he was to discover that neither Deputy nor aristocrat was to be found.

Brutus informed him that he was expecting the Citizen La Boulaye, but beyond that he would say nothing, and he wisely determined to hold his peace touching the valise that he had been ordered to pack and the fact that he knew the Deputy meditated leaving Paris.

Brutus had learnt the value of silence, especially when those who sought information were members of the Convention.
Alarmed at this further corroboration of Cecile's story of treachery Varennes left the military at Caron's house, with orders not to allow the Deputy to again depart if in the meantime he should happen to return, whilst to every barrier of Paris he sent instructions to have La Boulaye detained if he should present himself.
