It was but twice that I must stoop to that ungrateful necessity of playing spy. I was then certain of my lord's purpose in his rambles and of the secret source of his delight. Here was his mistress: it was hatred and not love that gave him healthful colours. Some moralists might have been relieved by the discovery; I confess that I was dismayed. I found this situation of two brethren not only odious in itself, but big with possibilities of further evil; and I made it my practice, in so far as many occupations would allow, to go by a shorter path and be secretly present at their meeting. Coming down one day a little late, after I had been near a week prevented, I was struck with surprise to find a new development. I should say there was a bench against the Master's house, where customers might sit to parley with the shopman; and here I found my lord seated, nursing his cane and looking pleasantly forth upon the bay. Not three feet from him sate the Master, stitching. Neither spoke; nor (in this new situation) did my lord so much as cast a glance at his enemy. He tasted his neighbourhood, I must suppose, less indirectly in the bare proximity of person; and, without doubt, drank deep of hateful pleasures.

He had no sooner come away than I openly joined him.

"My lord, my lord," said I, "this is no manner of behaviour."

"I grow fat upon it," he replied: and not merely the words, which were strange enough, but the whole character of his expression, shocked me.

"I warn you, my lord, against this indulgency of evil feeling," said I. "I know not to which it is more perilous, the soul or the reason; but you go the way to murder both."

"You cannot understand," said he. "You had never such mountains of bitterness upon your heart."

"And if it were no more," I added, "you will surely goad the man to some extremity."

"To the contrary; I am breaking his spirit," says my lord.

Every morning for hard upon a week my lord took his same place upon the bench. It was a pleasant place, under the green acacias, with a sight upon the bay and shipping, and a sound (from some way off) of mariners singing at their employ. Here the two sate without speech or any external movement, beyond that of the needle, or the Master biting off a thread, for he still clung to his pretence of industry; and here I made a point to join them, wondering at myself and my companions. If any of my lord's friends went by, he would hail them cheerfully, and cry out he was there to give some good advice to his brother, who was now (to his delight) grown quite industrious. And even this the Master accepted with a steady countenance; what was in his mind, God knows, or perhaps Satan only.
