The hotel came into view: the ‘Ice Palace’. These days, all new buildings in London seemed to acquire nicknames – the Gherkin, the Cheese Grater and so on. And Ice Palace sounded better than ‘Battersea Regina’ – some smartarse had already called its giant three-storey atrium the Battersea Vagina. True to its name, though, this one looked the part, all tiered glass, like something that had time-travelled out of the future. And, like all good palaces, it was surrounded by a vast fortified wall to keep out any trouble. But not the river front. Didn’t the architects have any sense of history?

As the craft made its way towards the target, he reviewed his route once more. He was right to avoid going through the kitchens. Unless he could slip past the staff he would have to take down whoever was there, which would be messy and risky. He didn’t want collateral: there was only one target. The better option was through the laundry. He smiled grimly as he thought of the heavy security out front, ever vigilant, never imagining the threat that was coming by river on a frozen February night.

He slowed as the hotel came into view. A giant slab of glass and concrete bordering the southern bank of the river, so new there were still traces of the last construction work. He unclipped the oars and dropped their paddles into the water. Short, shallow scoops brought the craft noiselessly up to the jetty.

Over his shoulder he spotted a lone silhouetted figure on the broad apron that separated the hotel from the river, leaning against the balustrade, the orange dot of a cigarette glowing minutely as the smoker drew on it. The figure straightened, the cigarette suspended in front of him. As he watched, he unzipped the suit, felt for the Glock. One well-aimed shot and it would be that smoker’s last gasp. But before he drew down his weapon the man flicked the butt into the water, turned and ambled back out of the cold.

The craft nudged the jetty and he reached for one of the polystyrene bumpers that dangled from it, tugged it and drew the craft towards a metal gangway. The whole structure was encased in a thick glaze of ice. He struggled for grip through the waterproof gloves. The boat slid from under him and, for a few seconds, he feared he would drop into the icy river. He was out of shape: he hadn’t done shit like this in a long while. After several tries he managed to haul himself high enough to get one foot on the structure. Then he kicked the inflatable away. He wouldn’t be needing it. Maybe someone down-stream, Gravesend perhaps, would be the lucky owner of a new boat by the end of the night. There was no exit from this, no going back now.
