“There is nothing, Excellency,” he said. “The plaster is cracked. But—— Ah!”

In a panic of haste Gonzaga had whipped the dagger from its sheath and sunk it into the middle of Aventano's broad back. The fellow's arms slid out, and with a long-drawn, gurgling sigh he sank down and stretched himself horribly on the stones.

In that instant the clouds parted overhead and the sun came out in a blaze of golden glory. High above Gonzaga's head a lark burst into song.

For a moment the assassin remained standing above the body of his victim with head sunk between the shoulders like a man who expects a blow, his face grey, his teeth chattering, and his mouth twitching hideously. A shudder shook him. It was the first life he had taken, and that carrion at his feet filled him with sickly horror. Not for a kingdom—not to save his vile soul from the eternal damnation that act had earned it—would he have dared stoop to pluck the dagger from the back of the wretch he had murdered. With something like a scream he turned, and fled in a panic from the spot. Panting with horror, yet subconsciously aware of the work he had to do, he paused a moment to wave a kerchief, then dashed down the steps to the postern.

With trembling fingers he unlocked the door and set it wide to Gian Maria's men, who, in answer to his signal, were now hurrying forward with a bridge composed of pine trees, that they had hastily and roughly put together during the previous day. This, with some efforts and more noise than Gonzaga relished, was thrust across the moat. One of the men crept across, and assisted Gonzaga to make fast his end.

A moment later Gian Maria and Guidobaldo stood in the castle-yard, and after them came almost every man of the five score that Gian Maria had brought to that siege. This was what Francesco had confidently expected, knowing that it was not his cousin's way to run any risks.

The Duke of Babbiauo, whose face was disfigured by a bristling hedge of reddish stubble—for in obedience to the vow he had made, he now carried a fortnight's growth of beard on his round face—turned to Gonzaga.

“Is all well?” he asked, in a friendly tone, whilst Guidobaldo contemptuously eyed the popinjay.

Gonzaga assured them that the whole thing had been effected without disturbing the garrison at their prayers. Now that he deemed himself well protected his usual serenity of manner returned.

“You may felicitate yourself, Highness,” he ventured to say, with a grin, to Guidobaldo, “that you have reared your niece in devout ways.”
