As they would now be leaving before Roger's return from Toledo it was his last chance to talk to them about his own plans. Colonel Thursby, with a kindness typical of him, said that when Roger and Isabella reached London they were welcome to occupy his house in Bedford Square until they could find a place to live permanently, and Georgina said that Stillwaters would always be at their disposal. But suddenly, just as Roger was about to take his leave, she stood up, faced him squarely, and said:
"I still cannot bring myself to believe in the poison plot. I beg you, Roger, to give me your assurance that had you not been informed of it, and had some earlier opportunity occurred to revive your intimacy with the Condesa, you would still have formed this determination of eloping with her as soon as she had been delivered of her child?"
Roger had never told Georgina a lie in his life, and he could not bring himself to do so now.
"Nay," he said quietly. "I fear I cannot give you that assurance. After I left Naples I counted the matter as a chapter in my life that was closed. But I am deeply attached to Isabella and believe that we shall be happy. In any case, my honour is now involved in it, and nothing would induce me to draw back."
Feeling there was no more that she could say, she let him go. But no sooner was he outside the door than she burst into tears at the thought of the trouble she believed him to be laying up for himself;
and her wise, adoring father could think of little to say to bring her comfort as she sobbed again and again:
" 'Tis a tragedy, a tragedy! I would give ten years of my own life could I but think of some way to prevent it."
Roger slept ill on account of his anxiety for Isabella, and he had puzzled his wits in vain for some way of assuring himself that no ill had befallen her before he set off for Toledo; so, when the Caballero Heredia called for him at eight o'clock, he had to start on his trip still ignorant whether Don Diego had utilized his last night but one in Aranjuez to attempt her murder.
The day was fine and the drive pleasant, as the road lay for the whole thirty miles they had to cover along the banks of the Tagus, and the tortuous course of the river provided variety in an otherwise flattish landscape. Had Roger not been so worried for Isabella he would have thought even the distant sight of the ancient capital of Spain well worth the long drive, as it was set on a rugged pinnacle of granite, the foot of which was washed on three sides by a great bend in the river, and its towers, battlements and spires rising tier after tier against the blue sky made it look like a fairy city.
After the siesta they visited the Cathedral and in its treasury saw the image of the Virgin, roped with millions of doubloons' worth of pearls and other gems, that is carried in procession through the street on feast days; but Roger was more interested in the strange, distorted, greenish-hued paintings by El Greco that hung in the chapels of many of the lesser churches. He was, too, fascinated by the unusual silence that pervaded so large a city, on account of the cobbled ways between its old Moorish buildings being mostly too steep and narrow to permit the passage of traffic. In the evening they went to the fortress-palace of the Alcazar, where the Governor entertained them to a meal and provided them with accommodation for the night.
On the Thursday morning they set off early on the return journey and were back in Aranjuez just before midday. In normal circumstances Roger would have enjoyed the excursion enormously, and he did his best to show his appreciation to Heredia; but he got rid of the Caballero at the earliest possible moment in order to hurry round to the Sidonia y Ulloa mansion.
When visiting the pavilion earlier in the week he had never seen anyone about the grounds during the siesta hour and, had he done so, he could have said that he was calling on his compatriot, Colonel Thursby. Now he no longer had that excuse he wondered a little anxiously if his luck would hold, and he would continue to escape observation. But that anxiety was a small matter compared with the acute one to reassure himself that Isabella had come unharmed through her husband's last two days in Aranjuez.
As he hurried down the avenue he saw Quetzal standing outside the gate. An awful doubt seized upon his mind. Had Isabella stationed the boy there to warn him that there was someone in the grounds or was he, knowing that she expected her lover, waiting there to break some ghastly news ?
A moment later Quetzal caught sight of him and began to run in his direction. During his visit to Naples, and while in Aranjuez, Roger had not seen the little Indian, so it was over ten months since they had met. He thought the youngster had grown considerably, and his education had evidently progressed; as, when he was still some twenty yards off, he broke out into heavily accented but quite understandable French:
"Monsieur le Chevalier! I have a carriage waiting. We are to collect your things and set out at once for Madrid."
"For Madrid 1" echoed Roger. "In God's name, why?"
"Yes. They will sup and rest there before proceeding further. If we start at once we can catch them up by nightfall. My mistress said you could give as an excuse for joining them a belated thought that you would like to make the journey to Paris in the company of your English friends."
"What the devil are you talking about?" Roger exclaimed. "I have no wish to go to Paris. I could not, even if I had, as important matters detain me here. Tell me at once"
"But you must! You must!" the boy broke in. "Did you not come to Spain to save my mistress?"
"Indeed I did!"
"Then how can you allow aught else to detain you?"
Quetzal's black eyes were now flashing angrily, and Roger, still at a loss to understand what lay behind his excited words, cried with puzzled impatience:
"Mort Dieu! Be plain with me. Is your mistress still alive and well ?"
"Would I be here if she were not?"
"Thank God for that! Then take me to her."
"Am I not begging to do so ? The carriage waits."
"What! Mean you that she has gone to Madrid?"
"Have I not said so, Monsieur?"
**You had not! But why? Why has she gone? Is it that she has accompanied them on the first stage of the journey, and means to see them off from the capital?"
"It was the Queen, Monsieur. Yesterday Her Majesty learned of my mistress's decision to remain here with her baby. She was angry. She said that the name Sidonia y Ulloa means nothing in Paris; but that of d'Aranda everything. That 'tis not Don Diego, but my mistress, who is the friend of Madame Marie Antoinette, and so can help to win her support for the cause of Spain. Last night there came with all this I tell you an imperative order from the Queen. So my mistress is still with that fiend who would murder her, and now on her way to Paris."
CHAPTER TWENTY-FOUR
THE OUTCOME OF THE MISSION
ROGER stood aghast, staring in dismay at the young, brown-faced Aztec Prince with the beautifully embroidered clothes and gaily feathered headdress. The plot that he and Isabella had hatched for getting Don Diego sent to Paris had recoiled on their own heads. They had been too clever, and were now hoist with their own petard; or at least separated by it more effectually than they could have been by anything else short of death or prison.
"For what are you waiting, Monsieur?" The little Indian grasped his sleeve and pulled at it impatiently. "Every moment is precious!"
"I have told you," Roger muttered, shaking off his hold. "I cannot go to Paris."
"Cannot go to Paris ?" Quetzal repeated in astonishment. "Do you mean that you abandon my mistress?"
Roger bit his lip, then burst out: "God knows I have no wish to! But 'tis impossible for me to leave Aranjuez. I have business here that no other person can handle for me."
