She powered along King’s Parade towards Trumpington, weaving in and out of the patchy light. Somewhere not far away, a breakfast was cooking, for the air held the faint scent of bacon and coffee. Her throat began to close uneasily in response, and she increased her speed to escape the odour, splashing through a puddle that sent icy water seeping through her left sock.

At Mill Lane, she made the turn towards the river. The blood was beginning to pound in her veins, and in spite of the cold, she had started to perspire. A line of sweat beneath her breasts was trickling towards her waist.

Perspiration’s the sign that your body is working, her father would tell her. Perspiration, naturally. He would never say sweat.

The air seemed fresher as she approached the river, dodging two dust carts that were manned by the first living creature she had seen out on the streets this morning, a workman wearing a lime green anorak. He heaved a haversack onto the pushbar of one of the carts and lifted a thermos as if to toast her as she passed.

At the end of the lane, she darted onto the pedestrian bridge that spanned the River Cam. The bricks beneath her feet were slick. She ran in place for a moment, fumbling with the wrist of her track jacket to get a look at her watch. When she realised she’d left it back in her room, she cursed softly and jogged back across the bridge to have a quick look down Laundress Lane.

Damn, damn, double damn. Where is she? Elena squinted through the fog. She blew out a quick gust of breath in irritation. This wasn’t the first time she’d had to wait, and if her father had his way, it wouldn’t be the last.

“I won’t have you running alone, Elena. Not at that hour of the morning. Not along the river. We won’t have any discussion about this. If you’d care to choose another route…”

But she knew it wouldn’t matter. Another route and he’d only come up with another objection. She should never have let him know that she was running in the first place.
