Continuity mistake: In chapter 9, Fireheart takes Cinderpaw to see the Thunderpath. He asks her if she can smell anything apart from the monsters, she replies that she can smell shadowclan because she smelt the same scent on the kits that were taken: 'I remember that scent from when brokenstar attacked our camp. And it was on the kits he took'. But if you read the paragraph about finding the kits in shadowclan (very end of chapter 24 in Into the Wild) it says that "the last one was grey, like the embers of an old fire" and that she is a girl. The description sounds like Cinderpaw, and she is one of Frostfur's kits (like the ones who were taken), which means Cinderpaw was taken but says the scent was on the ones he took, meaning she wasn't one.
Continuity mistake: In the chapter called "The Park," when Grant sees the T-Rex, he states that the T-Rex was sleeping by the killed hadrosaur. Then later on in the same chapter, it says the juvenile T-Rex stood over the T-Rex's killed sauropod. It even goes on to say that the juvenile T-Rex steals a piece of meat from this sauropod and runs away with it. Sauropods and hadrosaurs are different dinosaurs.
Continuity mistake: The detective Kinsey Millhone is looking through her closet for something to wear to a party and comes across a green cocktail dress that was given to her in E is for Evidence that she "forgot she had". However, in E is for Evidence, Kinsey was hurt in a bomb blast and specifically says that this dress was cut off her in the emergency room so her wounds could be treated. Even if she bothered having the dress repaired, it was unlikely she would have forgotten about it, especially under the circumstances.

Continuity mistake: Towards the end of the book (p. 361 in my paperback edition) there is a chapter called "The Fifteenth Day: Friday, 17 December." The mistake is that the next chapter is called "The Sixteenth Day: Saturday, 17 December". The book has December 17th occurring two days in a row.
Continuity mistake: In "A Kiss of Shadows" by Laurell K Hamilton at the beginning of chapter 8 it states that "It's eight o'clock Friday night". At the beginning of chapter 10 it says "Eight o'clock on a Saturday night". Between these two chapters only and hour or so of time has passed by. So which day is it, Friday or Saturday?
Continuity mistake: In the previous book, Dark Assassin, Monk goes through Durban's notes and finds the only case of his which "remained a mystery" (Ch. 7). The case Monk reopens in the next book, Execution Dock, is also repeatedly referred to as "the one case Durban had not solved" (e.g., Ch. 1 and Ch. 5). The mistake is that there is no way these are the same case. The one from Dark Assassin involves the murder of a 40-year-old barber named Roger Thorwood; the one from Execution Dock is the sexual abuse and murder of a boy named Walter Figgis, by a man named Jericho Phillips. None of the suspects, victims, or witnesses in the two cases overlap at all. Of course Durban could have worked on both cases - but they can't both be the one single case he never solved. And if they are both unfinished, then it is wrong to say (as the author does repeatedly in Execution Dock) that there is only one case Durban didn't close. (It also can't be a character mistake on Monk's part, since he knows about both cases).
Continuity mistake: In Ch. 72, Stu describes finding Harold dead, and recalls that "Harold still clutched the Permacover notebook in one stiffening hand." But earlier, in Ch. 64, Stephen King states that Harold "put the Permacover notebook into the Triumph's saddlebag" immediately before shooting himself.
Continuity mistake: When Decker is reviewing the witness statements, he read that Melissa Dalton was at school early to take a make-up test, due to missing it for an illness. He then immediately notes that she had perfect attendance; she hadn't even had a tardy.

Barney rescues Valancy from the rowdy dance shortly after 11 pm (Ch. 20), and takes her away in his car, which runs out of gas. They sit and talk for a long time (Ch. 21), until Valancy's uncle and cousin drive up. which supposedly happens at 10 pm - an hour before they even left.
