When DI Barton is asked to investigate a seemingly innocuous fire that kills, he believes it's either children fooling around or a worrying racially motivated crime. As he delves deeper into the case, he soon realises that there is a history of similar blazes spread out over many years, all within a close area. And after an idea is suggested by pathologist Mortis, Barton suspects he has the arsonist's motives wrong. When a night worker comes forward with a tip, Barton narrows down the suspects. Yet all of them act suspiciously and he knows for sure that one or more of them are lying. And when a huge house blaze shocks everyone, Barton fears the killer has lost all control. Who is The Fire Killer? What will be next to burn?
