She didn't see Nish. The prisoners were kept apart, save for Flydd and Irisis, and each was surrounded by burly guards. All the men of Ghorr's guard were tall and Nish, a small man, would not be visible behind them.

Ullii went back and forth, testing the air for every tendril of odour, and, around the corner, picked up an old scent. She could even tell that Nish had been weary when he'd come this way. He'd plodded down the corridor before stopping for a moment. Why? Ullii smelt Irisis's fresh, creamy tang and her fists clenched involuntarily. Nish and Irisis had been lovers once, before Ullii had met him. She sniffed the air. He'd gone into her room!

She tracked him to the bed and he'd been in it. He'd lain with Irisis just hours ago. How dare he? Ullii didn't operate on logic – as far as she was concerned, Nish had been hers ever since they'd made love in the balloon in the treetops near Tirthrax, at the end of last winter. He'd made her pregnant there, and even though he'd killed her brother since then, she would share him with no one.

It firmed her faltering resolve. She tracked Nish to his little room. The bed was cold but a fresher scent led around the corner, into the main hall and up in the direction of the front door. There she lost it.

Ullii crept along the hall on her toes, keeping to the left-hand wall, ready to dart away should someone approach. She could hear the guards talking in the yard, gravel crunching under their boots and an occasional mutter or plea from the bound prisoners, always answered with a jeer or slap.

She headed for the stairs to one of the tower balconies she'd seen from Ghorr's air-dreadnoughts, so she could look down into the yard. A few steps up, she detected Nish's spoor once more, and it was fresher. He'd gone this way in the last few hours.
