He took the train out to Canning Town station. It was overlooked by Canary Wharf, whose sleek, futuristic buildings resembled a series of gleaming metal blocks on the horizon; their size, like that of the national debt, impossible to gauge from such a distance. But a few minutes’ walk later, he was as far from the shining, suited corporate world as it was possible to be. Crammed up alongside dockside developments where many of those financiers lived in neat designer pods, Canning Town exhaled poverty and deprivation. Strike knew it of old, because it had once been home to the old friend who had given him Brett Fearney’s location. Down Barking Road he walked, his back to Canary Wharf, past a building with a sign that advertised ‘Kills 4 Communities’, at which he frowned for a moment before realising that somebody had swiped the ‘S’.

The Ordnance Arms sat beside the English Pawnbroking Company Ltd. It was a large, low-slung, off-white-painted pub. The interior was no-nonsense and utilitarian, with a selection of wooden clocks on a terracotta-coloured wall and a lividly patterned piece of red carpet the only gesture to anything as frivolous as decoration. Otherwise, there were two large pool tables, a long and accessible bar and plenty of empty space for milling drinkers. Just now, at eleven in the morning, it was empty except for one little old man in the corner and a cheery serving girl, who addressed her only customer as ‘Joey’ and gave Strike directions through the back.

The beer garden turned out to be the grimmest of concrete back yards, containing bins and a solitary wooden table, at which a woman was sitting on a white plastic chair, with her fat legs crossed and her cigarette held at right angles to her cheek. There was barbed wire on top of the high wall, and a plastic bag had caught in it and was rustling in the breeze. Beyond the wall there rose a vast block of flats, yellow-painted and with evidence of squalor bulging over many of the balconies.

‘Mrs Higson?’

‘Call me Marlene, love.’

She looked him up and down, with a slack smile and a knowing gaze. She was wearing a pink Lycra vest top under a zip-up grey hoodie, and leggings that ended inches above her bare grey-white ankles. There were grubby flip-flops on her feet and many gold rings on her fingers; her yellow hair, with its inches of greying brown root, was pulled back into a dirty towelling scrunchie.

‘Can I get you a drink?’

‘I’ll have a pint of Carling, if you twist my arm.’

The way she bent her body towards him, the way she pushed straw-like strands of hair out of her pouchy eyes, even the way she held her cigarette; all were grotesquely coquettish. Perhaps she knew no other way of relating to anything male. Strike found her simultaneously pathetic and repulsive.
