Det kan ha varit Max Brooks Zombie Survival Guide . I avsnittet om Vapen och bekämpningsmetoder :
Finally, at five meters, we used the last bit of fuel in the flamethrower! The sons of bitches lit up like torches but just wouldn’t stop! One of them grabbed [Name Withheld], setting him on fire as it bit through his neck. I saw the rest of those things surround him as we took off for the jungle, a mob of burning bodies squatting down to tear another screaming human torch apart.
I avsnittet Brand :
Flesh — human, undead, or otherwise — takes a long time to burn. In the minutes or hours before a blazing zombie succumbs, it will become a walking — or to be perfectly accurate, a shambling — torch. Several cases have been recorded in which burning ghouls have done more damage, even caused more deaths, than they would have with only their fingernails and teeth.
Slutligen (och jag har inte tillgång till boken, så jag kan inte verifiera var den visade upp), nämner TV Tropes under Infernal Retaliation som också finns i Zombie Survival Guide :
"Established wisdom for modern zombie hunters: The only thing worse than a horde of zombies is a horde of flaming zombies."
De noterar också att omnämnande av faran med flammande zombier kommer upp i Världskriget Z också.
