Figulus squatted back under cover. Then, as cautiously as he could, Cato looked out on the open space before the well. His eyes strained for any sign of movement. The low moan of the wind frustrated his hearing, and so it was that in spite of the darkness he saw the enemy before he heard them. The dark outline of one of the ruins opposite shifted its shape, then a shadow slowly emerged from between two stone walls. A horseman. On the threshold of the open space he reined in, and sat quite still on his mount, as if sniffing the air for signs of danger. At length the horse whinnied and raised a hoof, scraping a dark gash through the snow. Then, with a clearly audible click of the tongue, the Briton urged his beast forward, towards the well. The dark shape moved slowly through the speckled swirl and Cato got a clear sense that the man’s eyes were scouring the silent ruins. He hunched down behind the wall as far as he could go and still see over the blackened stonework. As the horseman reached the well, he reined in again, then edged alongside the rim for a better view down the well shaft. Cato’s hand tightened on the handle of his sword, and for a moment the temptation to draw the weapon was almost unbearable. Then he forced himself to release his grip. The men around him were tense enough to jump into action at the slightest hint that he was preparing to rush into the attack. They must wait for the trumpet. Hortensius was watching from the top of a burial mound outside the settlement and would only give the signal to spring the trap when all the raiders had passed inside the ruins of the main gate. The orders were clear: no man must move an inch until the signal was given. Cato turned towards his men, silently waving them down. From the way they were crouched and holding their shields and javelins ready, he could see that they were ready to move.

By the well, the horseman casually leaned to the side, hawked up some phlegm and spat down the shaft. The cold ache for revenge inside Cato was momentarily fanned into a terrible burning rage that set the blood pounding through his veins. He fought back against the impulse, clenching his fists so tightly that he could feel the fingernails biting painfully into his palms. The Durotrigan seemed satisfied that no danger threatened him or his companions and casually turned his horse and trotted out of the settlement’s centre back towards the main gate. Cato faced his men.
