Angels of Death: Inside the Bikers’ Global Crime Empire by William Marsden and Julian Sher is an investigative true-crime account of the Hells Angels and the international network of outlaw motorcycle gangs. The authors examine the gang’s expansion across countries including the United States, Canada, Australia and parts of Europe, exploring organised crime, drug trafficking, violence and conflicts between rival biker gangs. Drawing on police investigations, undercover operations, eyewitness accounts and interviews with gang members, the book provides a detailed look inside the criminal networks and the efforts of law enforcement to dismantle them.
