The human mind is a mysterious labyrinth, where eerie secrets can sometimes be discovered in secluded corners... Michael Havelock, a retired intelligence agent, is about to start a new, calm life. In fact, he has already been sentenced. Sentenced because of those half-erased events that happened in his other life. Somewhere in Havelock’s brain is hidden a key, a code sequence of words and signs that firmly connects him with the invisible manipulator of the destinies of mankind - the sinister Parsifal. And if Havelock manages to put together a mosaic of scattered, vague fragments of memory, he will figure out his secret Master and mortal enemy. Then he will finally receive the long-awaited peace and security. But Parsifal placed along this path psychological deceptions implanted in Havelock’s brain, and the main one is the memory of how a fair-haired girl was once killed on a sunny beach in the Costa Brava... But she is so similar to Jenna, to the woman whom Havelock loves, who is next to him... So who is he, the invisible Parsifal - is it Havelock himself?..
