Prince Ivan Petroffsky was a constant visitor at the Hotel Mars, and I began to take a certain interest in him, not unmingled with pity, for it was evident that he was hopelessly in love with my beautiful friend Zara. She received him always with courtesy and kindness; but her behaviour to him was marked by a somewhat cold dignity, which, like a barrier of ice, repelled the warmth of his admiration and attention. Once or twice, remembering what he had said to me, I endeavoured to speak to her concerning him and his devotion; but she so instantly and decisively turned the conversation that I saw I should displease her if I persisted in it. Heliobas appeared to be really attached to the Prince, at which I secretly wondered; the worldly and frivolous young nobleman was of so entirely different a temperament to that of the thoughtful and studious Chaldean philosopher.
Yet there was evidently some mysterious attraction between them--the Prince appeared to be profoundly interested in electric theories and experiments, and Heliobas never wearied of expounding them to so attentive a listener. The wonderful capabilities of the dog Leo also were brought into constant requisition for Prince Ivan's benefit, and without doubt they were most remarkable. This animal, commanded--or, I should say, brain- electrified--by Heliobas, would fetch anything that was named to him through his master's force, providing it was light enough for him to carry; and he would go into the conservatory and pluck off with his teeth any rare or common flower within his reach that was described to him by the same means. Spoken to or commanded by others, he was simply a good-natured intelligent Newfoundland; but under the authority of Heliobas, he became more than human in ready wit and quick obedience, and would have brought in a golden harvest to any great circus or menagerie.
He was a never-failing source of wonder and interest to me, and even more so to the Prince, who made him the subject of many an abstruse and difficult discussion with his friend Casimir. I noticed that Zara seemed to regret the frequent companionship of Ivan Petroffsky and her brother, and a shade of sorrow or vexation often crossed her fair face when she saw them together absorbed in conversation or argument.
One evening a strange circumstance occurred which startled and deeply impressed me. Prince Ivan had dined with us; he was in extraordinarily high spirits--his gaiety was almost boisterous, and his face was deeply flushed. Zara glanced at him half indignantly more than once when his laughter became unusually uproarious, and I saw that Heliobas watched him closely and half-inquiringly, as if he thought there was something amiss.
