post-mortem in a while.
âNo.â Professor Wilson wheeled around. âI want you to gather them into a little pile and set them on fire.â He glared. âOf course I want you to put the fucking things on. Unless you want to catch AIDS or whatever viral particles might be lurking in the bone dust thatâll fill the air when we take the oscillating saw around the victimâs skull. Alternatively, you can stand out there.â He waved a hand toward the large window that opened on to the corridor beyond. âBut youâll not be able to hear a fucking thing I say.â
âJesus,â Gunn said, as they pulled on their protective clothing in the pathologistâs room. âAnd I thought the CIO was bad.â
Fin laughed, and almost stopped dead at the sound of it. It was the second time he had laughed today, and he hadnât laughed in such a long time. Becoming aware of it, whatever he had thought amusing was quickly choked off by a tidal wave of returning emotion. He took a moment to recover himself. âAngus is okay. His barkâs worse than his bite.â
âIâd be frightened I caught rabies if he bit me.â Gunn was still reeling from the sharp edge of the pathologistâs tongue.
When they went back into the mortuary room, the professor had spread photographs across almost every available space. He was examining the victimâs clothes on the table. The stainless steel was covered by a large sheet of white butcherâs paper to collect any stray fibres or dried particles of vomit that detached themselves from the material. The victim had been wearing a zip-up fleece over a white cotton shirt and blue denim jeans. Big, dirty-white misshapen running shoes sat on the end of the table. The pathologist had slipped on his protective gloves and was holding a square magnifying glass in his left hand and picking delicately at the dried vomit on the dark blue fleece with a pair of tweezers. âYou didnât tell me the victim was my namesake.â
âThey never called him Angus,â Fin said. âEveryone knew him as Angel. You could send him a letter addressed to Angel, Ness, Isle of Lewis, from anywhere in the world and it would get to him.â
DS Gunn was shocked. âI didnât know you knew him, Mr. Macleod.â
âI was at school with him. His younger brother was in my class.â
âAngel â¦â Professor Wilson was still focusing on his tweezers. âDoes he have wings?â
âThe nickname was ironic.â
âAh. Maybe that explains why someone wanted to kill him.â
âMaybe it does.â
âGotcha, you little bugger!â The professor straightened up and held his tweezers up to the light, with what looked like a small white bead pinched delicately between its prongs.
âWhat is it?â Gunn said.
âItâs a ghost.â He looked at them, grinning. âOf a pill. One of these extended-release pills. The shell is full of micropores that let the medicine leak out slowly. This oneâs empty. But these pill casings can sometimes survive in the stomach for hours after theyâve served their purpose. We see them all the time.â
âIs there any significance in it for us?â Fin said.
âMaybe. Maybe not. But if this really is the killerâs vomit, then it could tell us something about him that we wouldnât otherwise have known. Whatever medicine this contained may or may not show up on a tox screen, but weâll still know what it was he was taking.â
âHow?â
The professor held up his magnifying glass to the tiny shell. âYou canât really see it with this, but stick it under a dissecting scope and weâll almost certainly find numbers or letters etched on the surface, even a drug company symbol. We can check the markings against those listed in drug books to identify the medication. It might take a little time, but weâll get
