He wrapped the rope around both arms, gave it another yank to be sure it was tied tightly above, and stepped up on the windowsill. He swung around so that he was facing the wall of the mansion and began to climb, his joy at her parting words making him feel stronger and more agile. His hands gripped the rough rope; his feet in calfskin boots pressed against the wall, pointed toes seeking out cracks. He did not look at the stone-paved street three stories below. He heard voices in the street--and froze. There were men gathered down there. If they looked up, they would see him climbing up the front of the cardinal's mansion. _Move quickly_, he told himself. He scrambled up to the square Guelfo merlon around which his rope was tied, pulled himself over the parapet, and dropped with relief to the flagstones of the flat roof. He untied the rope. Curiosity made him want to look at the men whose raised voices he heard coming from across the street. Something had disturbed them. But he had the feeling that if he did not look at them, they would not see him. _Hurry._ Holding the loosely coiled rope in one gloved hand, he ran as lightly as he could so as not to disturb anyone in the rooms below him. He came to the back of the building, where, two stories below him, a crenelated lower wall protecting the courtyard joined the main building. He uncoiled the rope, found its center, and doubled the line around an angled merlon at the corner of the roof battlements so that both halves dangled down just above the courtyard wall. Then, gripping the doubled rope, he swung himself out and began to climb down. A thunderous roar battered at his ears. He saw in the courtyard a big gray hound racing over the paving stones twice as fast as any man could run. It kept up a furious, enraged barking in a deep, bone-chilling voice. In an instant the dog was below him. Its bellowing was sure to rouse the cardinal's guards. Its huge, pointed white teeth glistened; its tail lashed from side to side. _If I fell, that damned dog would eat me alive._ He remembered seeing the dog before with Giancarlo, David of Trebizond's servant. It had been friendly enough that day. But now it saw him as an intruder. _Giancarlo called it by name. What the devil was it? If I could speak its name, maybe I could get it to shut up._ Simon stood on the courtyard wall, thankful that it was too high for the dog to reach him. The hound sprang at the top of the wall, at the same time emitting a bark so loud it almost knocked Simon off his perch. Simon pulled on one end of the rope, and it snaked around the merlon and came rippling down to him. To his horror, one end fell past him into the courtyard.
