Warning: The following material contains strong sexual content meant for mature readers. We strongly suggest storing this book in a place where young readers not meant to view it are unlikely to happen upon it. Stalker is a person who gets intimately familiar with little-known or forbidden areas and constructions. What will you do, if one day a stalker ends up breaching YOUR privacy? Invades your apartment, your house, maybe, your garden? What will you do, if such a person makes his or her appearance at the most unsuitable moment?
