This would not be the first morgue Strike had visited, and far from the first corpse he had viewed. He had become almost immune to the despoliation of gunshot wounds; bodies ripped, torn and shattered, innards revealed like the contents of a butcher’s shop, shining and bloody. Strike had never been squeamish; even the most mutilated corpses, cold and white in their freezer drawers, became sanitised and standardised to a man with his job. It was the bodies he had seen in the raw, unprocessed and unprotected by officialdom and procedure, that rose again and crawled through his dreams. His mother in the funeral parlour, in her favourite floor-length bell-sleeved dress, gaunt yet young, with no needle marks on view. Sergeant Gary Topley lying in the blood-spattered dust of that Afghanistan road, his face unscathed, but with no body below the upper ribs. As Strike had lain in the hot dirt, he had tried not to look at Gary’s empty face, afraid to glance down and see how much of his own body was missing… but he had slid so swiftly into the maw of oblivion that he did not find out until he woke up in the field hospital…

An Impressionist print hung on the bare brick walls of the small anteroom to the morgue. Strike fixed his gaze on it, wondering where he had seen it before, and finally remembering that it hung over the mantelpiece at Lucy and Greg’s.

‘Mr Strike?’ said the grey-haired mortician, peering around the inner door, in white coat and latex gloves. ‘Come on in.’

They were almost always cheerful, pleasant men, these curators of corpses. Strike followed the mortician into the chilly glare of the large, windowless inner room, with its great steel freezer doors all along the right-hand wall. The gently sloping tiled floor ran down to a central drain; the lights were dazzling. Every noise echoed off the hard and shiny surfaces, so that it sounded as though a small group of men was marching into the room.

A metal trolley stood ready in front of one of the freezer doors, and beside it were the two CID officers, Wardle and Carver. The former greeted Strike with a nod and a muttered greeting; the latter, paunchy and mottle-faced, with suit shoulders covered in dandruff, merely grunted.
