He never missed a night, always came and went alone, and never varied his proceedings in the least degree.
The manner of his watch was this.

At dusk, he entered the house in the same way as when the locksmith bore him company, kindled a light, went through the rooms, and narrowly examined them.

That done, he returned to the chamber on the ground-floor, and laying his sword and pistols on the table, sat by it until morning.
He usually had a book with him, and often tried to read, but never fixed his eyes or thoughts upon it for five minutes together.

The slightest noise without doors, caught his ear; a step upon the pavement seemed to make his heart leap.
He was not without some refreshment during the long lonely hours; generally carrying in his pocket a sandwich of bread and meat, and a small flask of wine.

The latter diluted with large quantities of water, he drank in a heated, feverish way, as though his throat were dried; but he scarcely ever broke his fast, by so much as a crumb of bread.
If this voluntary sacrifice of sleep and comfort had its origin, as the locksmith on consideration was disposed to think, in any superstitious expectation of the fulfilment of a dream or vision connected with the event on which he had brooded for so many years, and if he waited for some ghostly visitor who walked abroad when men lay sleeping in their beds, he showed no trace of fear or wavering.
