He ran a little way further, and waited. Ezio felt a glimmer of fear as the chasm of the street eight storeys below loomed before him, but he knew that he would die rather than hesitate in front of his brother, and so, summoning up his courage, he took a massive leap of faith, seeing, as he soared across, the hard granite cobbles in the moonlight far beneath his feet as they flailed the air. For a split second he wondered if he'd judged it right, as the hard grey wall of the palazzo seemed to rise up to meet him, but then, somehow, it sank below him and he was on the new roof, sprawling slightly it was true, but still on his feet, and elated, though breathing hard.

'Baby brother still has much to learn,' taunted Federico, setting off again, a darting shadow among the chimney-stacks under the scattering of clouds. Ezio hurled himself forward, lost in the wildness of the moment. Other abysses yawned beneath him, some defining mere alleyways, others broad thoroughfares. Federico was nowhere to be seen. Suddenly the tower of Santa Trinita rose before him, rising from the red sweep of the church's gently sloping roof. But as he approached he remembered that the church stood in the centre of a square, and that the distance between its roof and those of the surrounding buildings was far greater than any he had yet leapt. He dared not hesitate or lose speed now - his only hope was that the church roof was lower than the one he would have to jump from. If he could throw himself forward with enough force, and truly launch himself into the air, gravity would do the rest. For one or two seconds he would fly like a bird. He forced any thought of the consequences of failure out of his mind.

The edge of the roof he was on approached fast, and then - nothing. He soared, listening to the air whistle in his ears, bringing tears into his eyes. The church roof seemed an infinite distance away - he would never reach it, he would never laugh or fight or hold a woman in his arms again. He couldn't breathe. He shut his eyes, and then.
