He visits the "Lucky Inn," where the bartender lures him into a trap and attacks. King defeats him, noticing bite marks on his neck—clear evidence of a vampire thrall. King investigates Fred’s employer, Wyandanch Ltd., and discovers Dracula’s involvement. After a deadly confrontation and further leads, King learns Dracula killed Fred to cover coffin shipments.
