Leo examines a golden locket in a warmly lit manor study
Scene 01

The vanished locket

The dinner party has fallen silent. In the manor's cosy study — its walls lined with books and warm lamplight, more like a quiet café than a crime scene — a priceless heirloom locket has vanished from a room bolted from the inside. Leo, your sharp-eyed companion, turns to you: the game is afoot, detective.

Three uneasy guests: In the lamplit sitting room, three guests wait: a pale, anxious nephew, a composed old butler, and a sharp elderly aunt. Mira, the hostess, pours the tea and watches everyone over the rim of her cup. The nephew keeps glancing at the study door, twisting his napkin into knots.
Scene 02

Three uneasy guests

In the lamplit sitting room, three guests wait: a pale, anxious nephew, a composed old butler, and a sharp elderly aunt. Mira, the hostess, pours the tea and watches everyone over the rim of her cup. The nephew keeps glancing at the study door, twisting his napkin into knots.

The tender motive: Mira reveals the family portrait inside the golden locket
Scene 03

The tender motive

The clues and the questions lead to one quiet truth. The young nephew took the locket — but only because it holds his late mother's portrait, promised to him for years and then denied. He never meant to keep it; he only wanted to hold his mother's face one more night. Mira looks at you, torn.
