He died with his eyes open

"As it turns out, a dead man can tell stories ... Murders are a dime a dozen in Margaret Thatcher's London, and when it comes to the brutal killing of a middle-aged alcoholic found dumped outside of town, Scotland Yard has more important cases to deal with. Instead it's a job for the Department of Unexplained Deaths and its head Detective Sergeant. With only a box of cassette-tape diaries as evidence the rogue detective has no choice but to listen to the haunting voice of the victim for clues to his gruesome end. The first book in Derek Raymond's acclaimed Factory Series is an unflinching yet deeply compassionate portrait of a city plagued by poverty and perversion, and a policeman who may be the only one who cares about the 'people who don't matter and who never did.'"--Back cover.
