On leaving the house he had turned quickly into the rue Git-le-Coeur; but on hearing the door close behind his pursuer he disappeared down the narrow and crooked rue de l'Hirondelle, hoping to throw the Duc de Vitry off the scent.

The duke, however, though for a moment in doubt, was guided by the sound of the flying footsteps.

The chevalier, still trying to send him off on a false trail, turned to the right, and so regained the upper end of the rue Saint-Andre, and ran along it as far as the church, the site of which is occupied by the square of the same name to-day.

Here he thought he would be safe, for, as the church was being restored and enlarged, heaps of stone stood all round the old pile.

He glided in among these, and twice heard Vitry searching quite close to him, and each time stood on guard expecting an onslaught.
