Odo's impatience to be gone increased with every delay, and at length he determined to go forward at all adventure, leaving Cantapresto to conclude the preparations and overtake him later. It had been agreed with Trescorre that Odo, on his way to Pianura, should visit his grandfather, the old Marquess, whose increasing infirmities had for some years past imprisoned him on his estates, and accordingly about the Ascension he set out in the saddle for Donnaz, attended only by one servant, and having appointed that Cantapresto should meet him with the carriage at Ivrea. The morning broke cloudy as he rode out of the gates. Beyond the suburbs a few drops fell, and as he pressed forward the country lay before him in the emerald freshness of a spring rain, vivid strips of vineyard alternating with silvery bands of oats, the domes of the walnut-trees dripping above the roadside, and the poplars along the water-courses all slanting one way in the soft continuous downpour. He had left Turin in that mood of clinging melancholy which waits on the most hopeful departures, and the landscape seemed an image of anticipations clouded with regret. He had had a stormy but tender parting with Clarice, whose efforts to act the forsaken Ariadne were somewhat marred by her irrepressible pride in her lover's prospects, and whose last word had charged him to bring her back one of the rare lap-dogs bred by the monks of Bologna. Seen down the lengthening vista of separation even Clarice seemed regrettable; and Odo would have been glad to let his mind linger on their farewells. But another thought importuned him. He had left Turin without news of Vivaldi or Fulvia, and without having done anything to conjure the peril to which his rashness had exposed them. More than once he had been about to reveal his trouble to Alfieri; but shame restrained him when he remembered that it was Alfieri who had vouched for his discretion. After his conversation with Trescorre he had tried to find some way of sending a word of warning to Vivaldi; but he had no messenger whom he could trust; and would not Vivaldi justly resent a warning from such a source? He felt himself the prisoner of his own folly, and as he rode along the wet country roads an invisible gaoler seemed to spur beside him.
