This might perhaps have been possible, but it would have been quite impossible for him to bring his wife back by the same way.

There was a bell at the gardener's little gate, which he rang loudly; but no one would come to him.

At last he made his way round into the kitchen-garden by a corner where access was made by climbing a moderately high gate which gave an entrance to the fields.

From thence he had no difficulty in making his way on to the lawn at the back of the house, and up by half-a-dozen stone steps to the terrace which ran along under the windows.

Here he found that the lower shutters were barred on the inside throughout so that he could not look into any of the rooms.
But he could rap at the windows, which he did loudly, and it was in his power to break them if he pleased.
