This is a book that does exactly what it says on the tin, tells the story of stalkers and their victims. Included are some high-profile cases - Mark Chapman's fatal stalking of John Lennon, the Jill Dando murder, for example - but mostly the book recounts stories you won't have met before, ordinary citizens living ordinary lives until some other apparently ordinary citizen develops a pathological fixation.
In most hands this subject would be sensationalized to within an inch of its life. What makes this book so good is that its author recounts the facts with full journalistic detail but in a voice that never rises above those of the main characters. The facts really do speak for themselves, often in the form of chilling correspondence from predator to prey.
And those facts are often bewildering. Take Jeremy, who for years stalked a female presenter on his local TV channel. Among the masses of letters, cards and scripts, some of them complete with frightening illustrations, Jeremy sent her advice about what to do - if ever she had a stalker. This is the most common of all the phenomena, and the most baffling: the stalker's delusion that this is a relationship, that his feelings are reciprocated, that his actions are entirely natural and justified. A form of love. And if you thought stalking was a modern phenomenon, there's the story of Richard Archer Prince who became obsessed with the actor William Terriss and eventually stabbed him to death - in 1897.
'I'll Be Watching You' is a sensitive psychological study without any of the usual pitfalls, the psycho-babble and prurience and manufactured outrage. I'd recommend it to anyone interested in the criminal mind or simply in the weirder manifestations of human behaviour.
