In a couple of minutes he arrived at a pair of large gates.

They were closed, but he dismounted, fastened the bridle chain to them and, snatching the pistols from his holsters, ran along by the side of a high wall, until he came to a tree growing close to it.
With some difficulty, for his high boots were ill adapted to such work, he climbed the tree, got on to the wall, and dropped down.

He was in large park-like grounds.

Guided by a light in a window, he ran to the house.

The door was closed.
