Meanwhile, Atossa's hatred grew apace. She saw with anger that her power of tormenting Nehushta was gone from her, that the spirit she had loved to torture was broken beyond all sensibility, and that the man who had scorned her love was grown greater than she. Against his wisdom and the king's activity, she could do little, and her strength seemed to spend itself in vain. Darius laughed mercilessly at her cunning objections to Zoroaster's reforms; and Zoroaster himself eyed hear coldly, and passed her by in silence when they met.

She bethought herself of some scheme whereby to destroy Zoroaster's power by a sudden and violent shock; and for a time, she affected at more than usual serenity of manner, and her smile was sweeter than ever. If it were possible, she thought, to attract the king's attention and forces to some distant point, it would not be a difficult matter to produce a sudden rising or disturbance in Stakhar, situated as the place was upon the very extreme border of the kingdom, within a few hours' march across the hills from the uncivilised desert country, which was infested at that time with hostile and turbulent tribes. She had a certain number of faithful retainers at her command still, whom she could employ as emissaries in both directions, and in spite of the scene that had taken place at Shushan when Phraortes was brought to her by the king, she knew she could still command his services for a revolution. He was a Magian at heart, and hated the existing monarchy. He was rich and powerful, and unboundedly vain—he could easily be prevailed upon to accept the principality of Media as a reward for helping to destroy the Persian kingdom; and indeed the matter had been discussed between him and the queen long ago.

Atossa revolved her scheme in her mind most carefully for two whole months, and at last she resolved to act. Eluding all vigilance of the king, and laughing to herself at the folly of Darius and Zoroaster in allowing her such liberty, she succeeded without much trouble in despatching a letter to Phraortes, inquiring whether her affairs were now in such a prosperous condition as to admit of their being extended.

On the other hand, she sent a black slave she owned, with gifts, into the country of the barbarian tribes beyond the hills, to discover whether they could be easily tempted. This man she bribed with the promise of freedom and rich possessions, to undertake the dangerous mission. She knew him to be faithful, and able to perform the part he was to play.

In less than two months Phraortes sent a reply, wherein he stated that the queen's affairs were so prosperous that they might with safety be extended as she desired, and that he was ready to undertake any improvements provided she sent him the necessary directions and instructions.

The slave returned from the land of the dwellers in tents, with the information that they were numerous as the sands of the sea, riding like the whirlwinds across the desert, keen as a race of eagles for prey, devouring as locusts spreading over a field of corn, and greedy as jackals upon the track of a wounded antelope. Nothing but the terror of the Great King's name restrained them within their boundaries; which they would leave at a moment's notice, as allies of any one who would pay them. They dwelt mostly beyond the desert to eastward in the low hill country; and they shaved their beards and slept with their horses in their tents. They were more horrible to look upon than the devils of the mountains, and fiercer than wolves upon the mountain paths.

Allowing for the imagery of her slave's account, Atossa comprehended that the people described could be easily excited to make a hostile descent upon the southern part of the kingdom, and notably upon the unprotected region about Stakhar, where the fortress could afford shelter to a handful of troops and fugitives, but could in no wise defend the whole of the fertile district from a hostile incursion.

Atossa spent much time in calculating the distance from the palace to the fortress, and she came to the conclusion that a body of persons moving with some encumbrance might easily reach the stronghold in half a day. Her plan was a simple one, and easy of execution; though there was no limit to the evil results its success might have upon the kingdom.

She intended that a revolution should break out in Media, not under the leadership of Phraortes, lest she herself should perish, having been already suspected of complicity with him. But a man could be found—some tool of her powerful agent, who could be readily induced to set himself up as a pretender to the principality of the province, and he could easily be crushed at a later period by Phraortes, who would naturally furnish the money and supplies for the insurrection.

As soon as the news reached Stakhar, Darius would, in all probability, set out for Media in haste to arrive at the scene of the disturbance. He would probably leave Zoroaster behind to manage the affairs of state, which had centred in Stakhar during the last year and more. If, however, he took him with him, and left the court to follow on as far as Shushan, Atossa could easily cause an incursion of the barbarous tribes from the desert. The people of the south would find themselves abandoned by the king, and would rise against him, and Atossa could easily seize the power. If Zoroaster remained behind, the best plan would be to let the barbarians take their own course and destroy him. Separated from any armed force of magnitude sufficient to cope with a sudden invasion, he would surely fall in the struggle, or take refuge in an ignominious flight. With the boldness of her nature, Atossa trusted to circumstances to provide her with an easy escape for herself; and in the last instance, she trusted, as she had ever done, to her marvellous beauty to save her from harm. To her beauty alone she owed her escape from many a fit of murderous anger in the time of Cambyses, and to her beauty she owed her salvation when Darius found her at Shushan, the wife and accomplice of the impostor Smerdis. She might again save herself by that means, if by no other, should she, by any mischance, fall into the hands of the barbarians. But she was determined to overthrow Zoroaster, even if she had to destroy her husband's kingdom in the effort. It was a bold and simple plan, and she doubted not of being successful.
