Everything was ready to celebrate a fifth wedding anniversary when one of the celebrants suddenly and inexplicably vanished. What remained were signs of a struggle in the house, blood that someone had clearly tried to wipe away — and a chain of "clues" in a game called "treasure hunt"; the beautiful, clever, and incredibly inventive wife had organized it every year for her adored husband.
And it seems that these "clues" — the strange notes and equally strange trinkets she had placed here and there — offer the only chance to shed light on the fate of the missing woman. Except that the "hunter" may, in the course of the search, be forced to reveal a couple of his own rather unsavory secrets to the world.
