Circle spoiler alert
Spoiler: The hard part is figuring out who's lying...

Fortunately, if you arrange the characters incorrectly, Kaine will usually give a clue about what you did wrong. Unfortunately, there's a bug where he sometimes gives a clue about a suspect being in the wrong place when he's in the right place. But if you start out by calling everybody a liar, you should eventually get it right.
Circle spoiler alert
Spoiler: If you're really stuck, and just want to get it done...

Sarah(blond and has a green tail), Gary(holding trident, and has a brown tail), and Lucy(blond and has a red tail) are the liars.
