Toby Wilson's best friends from school, Callum and George, are starting to become more and more worried about Wilson's other friend and fellow student: the polite, mysterious Raymond. Is Raymond just foreign and a bit weird, or is he genuinely dangerous? If he is genuinely dangerous, would knowing the reason why be more dangerous than not knowing it? Wilson struggles to allay his friends' fears without lying to them or betraying Raymond; and then another problem appears: Raymond has a stalker. And she even knows the contents of his lunchbox. Wilson finds that he needs to learn to emulate Raymond's poise and acting ability very quickly – preferably without going mad, hurting any of his friends, or getting into huge amounts of trouble that would be extremely difficult to explain to adults.
Raymond's secret threatens to explode in his face – and take Wilson, Callum, and George with it – in this story, the third in the 'Raymond' series, about the 'sort-of vampire' and his long-suffering friend Wilson.
