He was home just as the clocks were striking six.  He was pale and upset, but otherwise looked strong and alert.  The old man summed up his appearance and manner thus:  “Braced up for battle.”

“Now!” said Sir Nathaniel, and settled down to listen, looking at Adam steadily and listening attentively that he might miss nothing—­even the inflection of a word.

“I found Lilla and Mimi at home.  Watford had been detained by business on the farm.  Miss Watford received me as kindly as before; Mimi, too, seemed glad to see me.  Mr. Caswall came so soon after I arrived, that he, or someone on his behalf, must have been watching for me.  He was followed closely by the negro, who was puffing hard as if he had been running—­so it was probably he who watched.  Mr. Caswall was very cool and collected, but there was a more than usually iron look about his face that I did not like.  However, we got on very well.  He talked pleasantly on all sorts of questions.  The nigger waited a while and then disappeared as on the other occasion.  Mr. Caswall’s eyes were as usual fixed on Lilla.  True, they seemed to be very deep and earnest, but there was no offence in them.  Had it not been for the drawing down of the brows and the stern set of the jaws, I should not at first have noticed anything.  But the stare, when presently it began, increased in intensity.  I could see that Lilla began to suffer from nervousness, as on the first occasion; but she carried herself bravely.  However, the more nervous she grew, the harder Mr. Caswall stared.  It was evident to me that he had come prepared for some sort of mesmeric or hypnotic battle.  After a while he began to throw glances round him and then raised his hand, without letting either Lilla or Mimi see the action.  It was evidently intended to give some sign to the negro, for he came, in his usual stealthy way, quietly in by the hall door, which was open.  Then Mr. Caswall’s efforts at staring became intensified, and poor Lilla’s nervousness grew greater.  Mimi, seeing that her cousin was distressed, came close to her, as if to comfort or strengthen her with the consciousness of her presence.  This evidently made a difficulty for Mr. Caswall, for his efforts, without appearing to get feebler, seemed less effective.  This continued for a little while, to the gain of both Lilla and Mimi.  Then there was a diversion.  Without word or apology the door opened, and Lady Arabella March entered the room.  I had seen her coming through the great window.  Without a word she crossed the room and stood beside Mr. Caswall.  It really was very like a fight of a peculiar kind; and the longer it was sustained the more earnest—­the fiercer—­it grew.  That combination of forces—­the over-lord, the white woman, and the black man—­would have cost some—­probably all of them—­their lives in the Southern States of America.  To us it was simply horrible.  But all that you can understand.  This time,
