Chapter One

So this was the Isle of Anglesey. Runcorn stood on the rugged headland and stared across the narrow water of the Menai Strait towards the mountains of Snowdonia and mainland Wales, and he wondered why on earth he had chosen to come here, alone in December. The air was hard, ice-edged, and laden with the salt of the sea. Runcorn was a Londoner, used to the rattle of hansom cabs on the cobbles, the gas lamps gleaming in the afternoon dusk. Every day he was surrounded by the sing-song voices of costermongers, the cries of news vendors, drivers of every kind of vehicle—broughams to drays—and the air carried the smell of smoke and manure.

This isolated island must be the loneliest place in Britain, all bare hills and hard, bright water, and silence except for the moan of the wind in the grass. The black skeleton of the Menai Bridge had a certain grace, but it was a cold elegance, not the low, familiar arches across the Thames. The few lights flickering on in the town of Beaumaris behind him indicated nothing like the vast city he was used to, teeming with the passions, the sorrow, and the dreams of millions.

Of course the reason he was here was simple. Runcorn had nowhere else in particular to be for Christmas, no family. He lived alone. He knew many people, but they were colleagues rather than friends. He had earned his promotions until he was now, at fifty, a senior superintendent in the Metropolitan Police, separated by office from those he had once worked beside. But he was not a gentleman, like those of his own rank. He had not the polish, the confidence, the ease of speech and grace of movement that comes with not having to care what people thought of you.
