She gave a little shriek.

The cavalier sprang forward, lifted his hat courteously, and joined her, bowing low.
The moonlight was full upon his face.
"It is Eustace, our cousin! How came he here, in the name of all the fiends ?" "Eustace! Then that is she, after all!" said Frank, forgetting everything else in her.
And now flashed across Amyas all that had passed between him and Eustace in the moorland inn, and Parracombe's story, too, of the suspicious gipsy.

Eustace had been beforehand with them, and warned Don Guzman! All was explained now: but how had he got hither?
"The devil, his master, sent him hither on a broomstick, I suppose: or what matter how?
Here he is; and here we are, worse luck!" And, setting his teeth, Amyas awaited the end.
The two came on, talking earnestly, and walking at a slow pace, so that the brothers could hear every word.
"What shall we do now ?" said Frank.

"We have no right to be eavesdroppers." "But we must be, right or none." And Amyas held him down firmly by the arm.
"But whither are you going, then, my dear madam ?" they heard Eustace say in a wheedling tone.

"Can you wonder if such strange conduct should cause at least sorrow to your admirable and faithful husband ?" "Husband!" whispered Frank faintly to Amyas.
