The author goes into the question of the close association of the then Edgar Caswall with Mesmer in Paris. He speaks of Caswall being a pupil and the fellow worker of Mesmer, and states that though, when the latter left France, he took away with him a vast quantity of philosophical and electric instruments, he was never known to use them again. He once made it known to a friend that he had given them to his old pupil. The term he used was odd, for it was 'bequeathed,' but no such bequest of Mesmer was ever made known. At any rate the instruments were missing, and never turned up."

A servant came into the room to tell Adam that there was some strange noise coming from the locked room into which he had gone when he came in. He hurried off to the place at once, Sir Nathaniel going with him. Having locked the door behind them, Adam opened the packing–case where the boxes of the two mongooses were locked up. There was no sound from one of them, but from the other a queer restless struggling. Having opened both boxes, he found that the noise was from the Nepaul animal, which, however, became quiet at once. In the other box the new mongoose lay dead, with every appearance of having been strangled!

CHAPTER X

THE KITE

On the following day, a little after four o’clock, Adam set out for Mercy.

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.
