Sir James Carnegie had not returned to England after the fall of Calais; he perceived that he was in grave disfavour with the Black Prince, and guessed, as was the case, that some suspicion had fallen on him in reference to the attack upon Walter in the camp, and to the strange attempt which had been made to destroy him by Sir Phillip Holbeaut. He had, therefore, for a time taken service with the Count of Savoy, and was away from England, to the satisfaction of Walter and Dame Vernon, when the marriage took place; for he had given proofs of such a malignity of disposition that both felt, that although his succession to the estates was now hopelessly barred, yet that he might at any moment attempt some desperate deed to satisfy his feeling of disappointment and revenge.

In spite of the gaiety of the court of King Edward a cloud hung over the kingdom; for it was threatened by a danger far more terrible than any combination of foes - a danger which no gallantry upon the part of her king or warriors availed anything. With a slow and terrible march the enemy was advancing from the East, where countless hosts had been slain. India, Arabia, Syria, and Armenia had been well-nigh depopulated. In no country which the dread foe had invaded had less than two-thirds of the population been slain; in some nine-tenths had perished. All sorts of portents were reported to have accompanied its appearance in the East; where it was said showers of serpents had fallen, strange and unknown insects had appeared in the atmosphere, and clouds of sulphurous vapour had issued from the earth and enveloped whole provinces and countries. For two or three years the appearance of this scourge had been heralded by strange atmospheric disturbances; heavy rains and unusual floods, storms of thunder and lightning of unheard-of violence, hail-showers of unparalleled duration and severity, had everywhere been experienced, while in Italy and Germany violent earthquake shocks had been felt, and that at places where no tradition existed of previous occurrences of the same kind.
